Introduction to Different Ultrasound Probes(2022年10月19日)

storkultrasonic — 2022-10-13T12:47:07+0900

https://www.storkultrasonic.com/products/

Ⅰ. What are the types of probes

It may be difficult to know which probe is appropriate for you when choosing an ultrasound system. To help you find the right probe, we will introduce different ultrasound probes.

1) Linear probe

The linear probe has a flat array and appearance. It is used to scan small and superficial structures, such as thyroid on the neck. The images linear probes produce are more square or rectangular.

2) Intrapleural probe

The intrapleural probe has a long handle, a U-shaped lens and array. It is used to scan inside the body. The depth range of this probe is limited to its shape, but it has a larger field of view than the convex probe.

3) Phased array / heart probe

The phased array / heart probe has a small handle, a square lens and array. Usually, it is used to scan the heart through pocket ultrasound machines. This probe has a deeper scan range and the ultrasound of this probe can reach the heart to produce images.

4) Transesophageal echocardiography (TEE) Probe

The transesophagel echocardiography (TEE) probe produces heart images through inserting into patients' esophaguses and stomachs. The probe is controlled by its handle and can move in four directions.

5) 3D / 4D Probe

The 3D probe performs the same function as the 2D probe with the exception of the moving array. The array inside the probe sweeps and captures image slices from different sides. The captured slices are then put together to produce either a 3D static image or a 4D real-time image.

Ⅱ. What is convex probe?
The convex probe (or curved linear probe) has a curved array, and provides a larger field of view. The convex probe is mainly used for abdominal scanning due to its larger and deeper field of view.

Different ultrasound probes are used in different medical fields. We are committed to providing solutions to the medical imaging field and improving the efficiency of diagnosis and treatment. Welcome to contact us if any other questions or immediate assistance.

What is the Piezoelectric Effect of an Ultrasound Transducer?(2022年10月18日)

storkultrasonic — 2022-10-13T12:46:35+0900

https://www.storkultrasonic.com/products/

The diasonograph generates incident ultrasound waves (transmitted waves) and receives reflected ultrasound waves (echoes) through probes. It is an important part of diagnostic equipment. The high-frequency electric energy excites the crystal in the probe to produce mechanical vibration, and the mechanical vibration of the reflected ultrasound wave can be converted into an electric pulse by the probe. That is to say, the probe can convert electric energy into sound energy, and it can also convert sound energy into electric energy, so the probe is also called an ultrasound transducer. The principle comes from the piezoelectric effect of the crystal.

1. Piezoelectric crystal of the ultrasound transducer

Crystals with piezoelectric effect properties are called piezoelectric crystals. At present, the crystal sheets commonly used in portable usg probe include artificial or natural crystals such as lead zirconate, barium titanate, quartz, and lithium sulfate. Barium titanate and lead zirconate are polycrystalline ceramic bodies sintered at high temperatures. After the blank is sintered into a ceramic body, it is properly ground and trimmed to obtain the required geometric dimensions. After polarization by a high-voltage direct current electric field, it has piezoelectric properties and becomes ultrasound transducer parts.

2. The piezoelectric effect of the ultrasound transducer
Positive piezoelectric effect

In a certain direction of the crystal or ceramic, mechanical force is applied to make it deform, and the two force-bearing surfaces of the crystal or ceramic produce charges with opposite signs; the direction of deformation is opposite, the polarity of the charge changes accordingly, and the charge density is proportional to the applied mechanical force. This effect of stimulating the surface charge due to the mechanical force is called the positive piezoelectric effect.

Inverse piezoelectric effect

Applying a voltage along the direction of the electric field on the surface of the crystal or ceramic will cause the geometric shape of the crystal or ceramic to be strained under the action of the electric field. The direction of the voltage changes and the direction of the strain also changes. The deformation is proportional to the electric field voltage. The deformation effect induced by the electric field is called the inverse piezoelectric effect.

In general, the piezoelectric effect is linear. However, when the electric field is too strong or the pressure is high, a nonlinear relationship will appear.

Crystals and ceramics have different natural frequencies of mechanical vibration due to the different cutting positions and geometric dimensions. When the frequency of the applied alternating voltage is consistent with the natural frequency, the mechanical vibration generated is the strongest; when the frequency of the applied mechanical force is consistent with the natural frequency, the generated charge is also the most. The frequency of the excitation pulse in the ultrasound diagnostic apparatus must be the same as the natural frequency of the ultrasound transducer.

Application of Stork Ultrasound in Peripheral Nerve(2022年10月16日)

storkultrasonic — 2022-10-13T12:45:25+0900

https://www.storkultrasonic.com/products/standard-linear-probe/

Ultrasound examination is one of the most timely and effective imaging methods for diagnosing peripheral neurological diseases. Ali and others from the University of Pennsylvania in the United States published an article in the 10th issue of World Neurosurgery in 2015 to introduce it in detail.

In the past, due to the low resolution of the handheld ultrasound probe, its value in diagnosing nerve injury was limited. However, with the improvement of ultrasound equipment and inspection technology (including the application of high-frequency probes and the improvement of scanning methods), the high-resolution images on the current advanced ultrasound equipment can show relatively small peripheral nerves. Its resolution is even higher than the most commonly used MRI inspection technology. Neuroelectrophysiological examinations can provide important diagnostic data such as the location and extent of neurological dysfunction. However, due to its own limitations, it is impossible to determine the morphological changes of nerves and the detailed types of nerve damage. Ultrasound examination can make up for this defect of neuroelectric physiological examination, and it will not cause pain to the patient.

The resolution of clinical MRI images is generally about 450 microns, while ultrasound images can reach higher resolutions. The axial resolution of the 10MHz probe can be close to 150 microns, while the current commonly used clinical 18MHz probe will have a higher resolution. Therefore, ultrasound can show the ultrastructure of each nerve more clearly and evaluate smaller nerves (such as peripheral nerves). In addition, ultrasound can also evaluate nerves near artificial implants, and MRI may be limited in the field.

Application of Stork Ultrasound in Peripheral Nerve

Stork's handheld wireless ultrasound probe

Stork ultrasonogram manifestations of normal peripheral nerves

Ultrasound examination should be carried out according to its anatomical shape. For example, the examination of the brachial plexus should start from the spinal nerve and the brachial plexus nerve trunk and extend to the end of the finger nerve. The operator's local anatomy knowledge and the shape of the examination site can affect the examination effect. Therefore, the operator must have anatomical knowledge of muscles, tendons, and blood vessels. At the same time, it is easier to find the location of nerves based on certain anatomical landmarks.

Brachial plexus

Median nerve

Ultrasound examinations of nerves mostly use a high frequency linear probe (8-18MHz), and different internal anatomical structures can show different echoes.

Stork'S Wireless High-Frequency Linear Array Probe

Stork's wireless high-frequency linear array probe

On the cross-sectional sonogram, the nerves appear as a hypoechoic structure, and small circular or oval hypoechoic areas can be seen inside, which are "honeycomb". The anatomical basis for this appearance is that hypoechoic tracts are separated by hyperechoic fascicles. The nerve gradually narrows into small branches as it travels from the proximal end to the distal end, and the perineurium also changes in different ways. Cross-sectional images are the most valuable for describing neuroanatomy and discovering lesions. The cross-sectional area of nerves is often used as an important parameter for the diagnosis of various neurological diseases.

On the ultrasonogram of the longitudinal section, the nerves run in a bundle. That means a linear high-level echo of the fascicular membrane can be seen within the hypoechoic tubular structure. Because the peripheral nerves are not straight and their diameter is relatively small, it is technically difficult to display the nerves through the longitudinal section. The cross-section perpendicular to the longitudinal section is especially helpful for finding abnormalities or changes in nerve contours.

Cross section of Ulnar nerve

Longitudinal section of Ulnar nerve

Nerves should be distinguished from the surrounding muscle tissue, which has lower echo than nerves. Comparing the thickness of the muscle around the nerve with the contralateral side can determine whether the muscle is normal and whether there is muscle atrophy due to obvious neuropathy. Tendons are different from muscles. Their echoes are higher than those of surrounding nerves, and they have a dense fiber shape. The dynamic examination of limbs can also help distinguish nerves from tendons. Color Doppler ultrasound can be used to identify nerves and blood vessels and detect increased blood flow signals and congestion caused by nerve compression or infectious neuropathy. Under normal circumstances, ultrasound shows that there is no blood flow signal distribution in the nerve bundle.

https://www.storkultrasonic.com/products/

With the continuous development of the medical level, ultrasound in the past half-century has also been improved significantly. From the previous gray, black, and white imaging to the current color imaging technology, from the traditional A-type ultrasound, M-type ultrasound to two-dimensional ultrasound, three-dimensional ultrasound, and four-dimensional ultrasound (real-time three-dimensional imaging technology), all of these embodied the development of ultrasound. Ultrasonography is of great clinical significance and can provide reliable data support for diagnosing diseases. In recent years, ultrasound examination has also been widely used in gynecology and obstetrics and has become a necessary means for diagnosing gynecological diseases and maternity examinations. Because ultrasound examination is safe and non-invasive, the operation is relatively simple, and the results are obvious, it has become an indispensable device for clinical diagnosis.

1. Application of Stork ultrasound in gynaecology

1.1 Diagnostic role of Stork ultrasound in gynaecology

Ultrasound examination can help doctors know the specific lesion area of uterine fibroids in detail. And it can also directly display the range of endometrial cancer invading the neck or the invasion of the myometrium and can make a judgment about whether endometrial cancer is benign. Like three-dimensional ultrasound imaging, the accuracy of detecting uterine malformations can reach 100%. Although two-dimensional ultrasound can also diagnose uterine malformations, it is still difficult to diagnose double horns and uterine longitudinals. The role of transvaginal ultrasound in diagnosing endometrial cancer is very crucial. The operation is performed according to the results of ultrasound examination, and the error is generally within 1mm. Through vaginal ultrasound examination, you can observe in detail whether the thickness of the endometrium is abnormal, whether the echo is uniform, whether the endometrial capsule is clear, etc., which can provide accurate digital data for clinical surgical treatment and ensure the safety of the operation.

1.2 Application of the measurement function of Stork ultrasound examination

Ultrasound can also measure volume. For patients with fibroids, doctors can use three-dimensional ultrasound to check. With ultrasound, doctors can measure the size of uterine fibroids and the size of endometrial polyps, and then provide powerful information support for subsequent treatment. Measuring the volume of the endometrium is clinically important. It can help distinguish whether the patient has endometrial cancer or benign lesions. Ultrasound can also accurately measure the size of the ovaries and follicles. If the patient suffers from an ovarian cyst or ovarian tumour, it can also accurately measure its volume, providing powerful data support for the patient's subsequent treatment. For patients with ovarian disease, transabdominal ultrasonography and transvaginal ultrasonography can be used. Ultrasound can observe whether the capsule of the tumour in the ovary is intact, whether the echo is uniform, whether there is a septum, etc. The doctor then refers to the RI value to determine whether the tumour is benign or malignant. Transvaginal ultrasound plays an important role in the early detection of ovarian tumours.

1.3 Role of hysterography and Stork color doppler ultrasound examination

In addition, the types of ultrasound are also divided into hysterography and color doppler imaging. Hysterography is very helpful in diagnosing uterine malformations and endometrial polyps, while Doppler ultrasound technology can clearly distinguish uterine muscles. The vascular structure of the tumor can be analyzed and imaged. If the tumor is malignant, the blood flow of the uterine artery is much higher than the normal arterial blood flow, and the blood flow in the tumor is relatively rich and benign. Compared with tumors, there are completely inconsistent manifestations, so ultrasound can provide a corresponding diagnostic basis for the clinical diagnosis of the nature of patients with uterine fibroids.

2. Application of Stork's ultrasound in obstetrics

2.1 Screening effect of Stork ultrasound on the fetus

In obstetrics, the application of ultrasound technology is also very extensive. Ultrasound can thoroughly check the development of the fetus in the mother's body. Ultrasound can determine whether it is a single birth or multiple births in time, and it can also detect the fetal heart rate of the fetus. Using ultrasound, doctors can check the embryos of abortion and a hydatidiform mole in time. And then doctors can terminate the pregnancy in time to protect the life of the pregnant woman. Generally, the fetus can be checked for malformation when the fetus is around 10W. The use of three-dimensional ultrasound in the deformity inspection can completely show the appearance and internal organs of the fetus. It can be screened for children with defects in appearance and children with underdeveloped internal organs, which is of great significance for high-quality fertility. The use of three-dimensional ultrasound in the first trimester can detect the presence of conjoined fetuses, and make corresponding judgments about its degree and type. The use of ultrasound can also make corresponding judgments on the growth of the fetus, including the fetus's limbs, double parietal diameter, and bone development, and the development of the spine.

In the third trimester of pregnancy, the use of ultrasound is the best way to monitor the growth of the fetus. It can understand the conditions of fetal overgrowth and developmental delay in time. At the same time, it can check the maturity level of the placenta, the position of the placenta, the depth of amniotic fluid, and fetal activities in detail. Especially when the parturient is about to give birth, ultrasound can accurately determine the position of the fetus, the size of the fetal limbs and double parietal diameter, the weight of the fetus, the maturity of the official neck, and the degree of opening, etc. At present, ultrasound is used as a crucial examination method for the whole pregnancy examination. After the birth, doctors can use ultrasound to observe the adhesion of the placenta of the parturient, the recovery of the uterus and the healing of the wound.

Fetal spine

Fetal head

Fetal heart blood flow

2.2 Application value of Stork interventional ultrasound in obstetrics

In addition, in obstetrics, interventional ultrasound is also very extensive. In the first trimester, interventional ultrasound can reduce multiple births. For pregnant women with oligohydramnios, normal saline can also be perfused. For the case that umbilical cord blood is required for examination, the examination can be conducted under the guidance of interventional ultrasound. Obstetric ultrasound equipment can diagnose the congenital diseases of the fetus in the mother's body, reduce the mortality of the fetus, and achieve the purpose of prenatal and postnatal care.

3. Application of Stork ultrasound in reproductive and gynaecological urology

The ultrasonic examination can observe the maturation and development of follicles, and at the same time make a diagnosis of factors that affect the development of follicles. Interventional ultrasound can also be used for vaginal egg retrieval, which is completely different from traditional abdominal egg retrieval to ensure that the patients receive non-invasive operations and the success rate of egg retrieval is effectively improved. In addition, the use of ultrasound in the diagnosis of stress urinary incontinence urinary dynamics is also very helpful. It can understand the stability of the bladder neck and make a judgment on the cause of the disease.

Application in obstetrics and gynecology-Stork portable handheld ultrasound scanner

In summary, the application of ultrasound examination in the field of obstetrics and gynecology is very extensive and necessary. Stork ultrasound examination also has the advantages of simple operation, safety and non-invasiveness, accurate clinical data, and congruent information. It has become an important inspection method in obstetrics and gynecology. Although ultrasound examinations are more accurate, clinicians are still needed. Doctors need to make a diagnosis of the patient's condition based on the ultrasound examination data and the specific situations of the patient, rather than just look at the ultrasound examination data and make a blind diagnosis.

Characteristics of the Ultrasound Transducer(2022年10月14日)

storkultrasonic — 2022-10-13T12:44:24+0900

https://www.storkultrasonic.com/products/

There are many characteristic parameters of ultrasound transducers, and only the following three are briefly introduced.

1. Frequency characteristics of the ultrasound transducer

The crystal of the portable ultrasound transducer itself is an elastic body, so it has its natural resonant frequency. When the frequency of the applied force is equal to its natural frequency, it will produce mechanical resonance, and the maximum electrical signal will be generated due to the positive piezoelectric effect. On the other hand, when the frequency of the applied electricity is the same as the natural frequency of the piezoelectric crystal, mechanical resonance should occur due to the inverse piezoelectric effect. The amplitude of resonance is the largest and the elastic energy is also the largest. At this time, the piezoelectric body obtains the maximum deformation vibration and produces ultrasound output through the medium. Experiments have proved that when the frequency of the applied force or electricity is not consistent with the natural frequency of the crystal, the amplitude of the electrical signal and the amplitude of the deformation vibration generated by the ultrasound transducer crystal will become smaller. It can be seen that they are both a function of frequency.

Frequency characteristics of the ultrasound transducer

If a certain value of voltage is applied to the piezoelectric crystal and the frequency of the applied voltage is changed, the loop current or impedance will change with it. When the voltage frequency is a certain frequency FM, the current has a maximum value Imax, and when the voltage frequency is another frequency fn, the current has a minimum value of Imin. The phenomenon that the current of the piezoelectric crystal changes with frequency (see the figure above) shows that the equivalent impedance of the ultrasound transducer crystal is a quantity that changes with frequency. If you continue to increase the frequency of the voltage, you can also find that a series of current fluctuations appear regularly, and the maximum value of the fluctuation (corresponding to fm1, fm2...) is sequentially reduced, while the minimum value of the fluctuation (corresponding to fn1, fn2... which is increasing in turn, FM is called the minimum impedance frequency of the piezoelectric vibrator (also called the maximum transmission frequency); fn is called the maximum impedance frequency (also called the minimum transmission frequency).

2. Transduction characteristics of the ultrasound transducer

The energy conversion characteristics of ultrasound transducers include two aspects: electrical energy-mechanical energy-ultrasound energy, and ultrasound energy-mechanical energy-electrical energy. The former belongs to the transmitting process, and the latter belongs to the receiving process. The conversion between energies will inevitably produce losses (producing unhelpful energy consumption), and the performance of the high frequency linear probe is characterized by the conversion efficiency:

Motor conversion efficiency = output mechanical power/input electrical power

Machine-to-sound conversion efficiency = radiated ultrasound power/input mechanical power

Therefore: Electroacoustic conversion efficiency=radiated ultrasound power/input electric power

3. Transient characteristics of the ultrasound transducer

Most of the ultrasound transducers work in the pulse state, and the response rate of the transducer to the pulse is called the transient characteristic, which is also an important indicator. The transient characteristics of a transducer are related to its frequency characteristics. In short, the wider the frequency spectrum of the transducer, the better its transient characteristics, and the narrower the allowable ultrasound pulse width. Here, the pulse width described refers to the length of time that the ultrasound is emitted intermittently, in seconds, which is different from the frequency (the number of ultrasound vibrations per second).

The probe is one of the most important components of the B supersonic diagnostic set. Ultrasonic probes can be classified from different aspects.

Types of ultrasound probes

(1) Classified by diagnostic location: There are ophthalmic probes, cardiac probes, abdominal probes, cranial probes, intracavitary probes, etc.;

(2) Classification by application: There are extracorporeal probes, intracorporeal probes, and biopsy probes;

(3) According to the number of vibration elements used in the transducer in the probe, there are unit probes and multi-element probes.

Use of different ultrasound probes

In the ultrasonic inspection process, the transmission and reception of ultrasonic waves are realized through the probe. The performance of the probe directly affects the characteristics of ultrasound and the imaging effect of ultrasound. Commonly used ultrasound probes include the phased array ultrasound probe, convex array probe and linear ultrasound probe.

(1) The phased array handheld ultrasound probe has a small surface area and is easy to scan the entire heart through the intercostal space. Generally, the frequency is lower, and the frequency of the pediatric phase-control array probe is slightly higher. It is mainly used for a heart scan, intracranial blood vessel scan and lung ultrasound scan, etc.

(2) The convex array probe has a large surface area, which is easy to scan various organs and spaces in the abdominal cavity. Generally, the frequency is low. The convex array probe for children is slightly higher, but the surface area of the probe is smaller. It is mainly used for abdominal and pelvic and other organ scans, FAST scans, pleural effusion scans, and lung ultrasound scans.

(3) The surface area of the linear probe is different. Generally, the frequency is high, so it is mainly used to scan musculoskeletal, blood vessels, superficial organs and tissues. With the widespread use of ultrasound in clinical practice, especially the use of four-dimensional ultrasound, 4D probes have become more and more popular.

Handheld Ultrasonic Instrument Becomes a Powerful Tool(2022年)

storkultrasonic — 2022-08-11T12:06:42+0900

https://www.storkultrasonic.com/handheld-ultrasonic-instrument-becomes-a-powerful-tool.html

When all medical staff have to wear protective clothing to work, they cannot realize daily diagnostic methods, such as look, listen and touch. Also, doctors rely on iconography and auxiliary examinations to diagnose diseases. The particularity of infectious diseases makes it inconvenient for patients to move, and for doctors to use bedside diagnosis. Ultrasonic diagnosis boasts the characteristics of repeatability, non-radiation, and high safety. The handheld ultrasound is flexible, compact and wireless, which is easy to disinfect and use. It can be used for the observation and evaluation of both emergency cases and severe cases. In addition, it can be used for real-time remote consultation based on the cloud platform, which effectively avoids cross-infection of medical workers.
In the middle of January, the early period of COVID-19, Shanghai Soundwise Technology Co., Ltd. and Chengdu Stork Healthcare CO., Ltd. donated handheld ultrasound device to Traditional Chinese Medicine Hospital of Sichuan and Chengdu 363 Hospital affiliated to Southwest Medical University.
In late January, the demand surged after the epidemic broke out, resulting in a relatively passive situation in the early stage. News of the shortage of supplies for hospitals in Wuhan was widely circulated. Zhang Zhuo, CEO of Soundwise Technology, said, "We heard from the first batch of Shanghai's first aid medical team in Hubei that flexible handheld ultrasound device is also urgently needed in the harsh environment of the frontline."
"In a special environment, a lot of equipment can't be used at all. But even with three layers of protection, Stork ultrasound equipment can still work. Because of the wireless design, the wireless portable ultrasound is more simple in disinfection. Doctors outside the isolation area can conduct remote consultation through communication to reduce cross-infection among medical workers. "
Stork handheld ultrasound equipment was first designed for first aid and field surgery application scenarios, which happened to come in handy in this incident.
At the time when Wuhan had already been in lockdown, Stork and Soundwise suffered a lot in order to deliver the first batch of handheld ultrasound equipment to front-line medical staff. When donating the second batch of materials to Wuhan, Stork and the Soundwise team thought of a way to parachute the equipment from the planes to Hubei.
The main purpose is to solve doctors' problems, rather than donate materials
After delivering the materials to Wuhan, Zhang Zhuo had thought he could take a rest, but they're still existed great challenges.
On the one hand, more medical teams hoped to have handheld ultrasound equipment after the first-line use in epidemic areas. Therefore, Stork and Shenzhen also sent the equipment to the aid medical teams of Zhejiang Province and Jiangsu Province.
On the other hand, how to optimally adapt doctors in special scenarios during the epidemic is also challengeable. During the COVID-19, doctors' understanding of the virus is deepening, and their demand for operation in the special environment is also increasing. Stork and Shenzhen hope to reduce the burden of doctors as much as possible and provide the best solution for doctors through continuous optimization.
Zhang Zhuo said: "in order to respond to the needs of the front line in a timely manner, the engineering team is 24 hours online to communicate the needs of doctors. For example, some doctors suggested that it was troublesome to label and input information, so we quickly equipped iFlytek's voice recognition system on the device, which could realize fast input."
In addition to responding to the special needs in the epidemic environment in a timely manner and adding specific modules, the biggest problem is that most doctors working in Wuhan are not professional ultrasound experts, so they are not familiar with ultrasound and need to learn how to use the instrument in a short time.
"We experienced a case where the first-line cardiologists in Wuhan encountered a lot of inconveniences when treating critically ill patients. As they are not professionals in the ultrasound field, they hope that the instrument has the functions of rapid diagnosis, automatic measurement, and preliminary judgment. Therefore, we embedded the artificial intelligence module in the instrument and completed these functions in one day for first-line doctors to directly obtain clinical parameters such as ejection fraction (EF), EDV, and ESV."
Since all doctors in Wuhan work in shifts 24 hours a day, Stork and Soundwise also respond to doctors' needs online all the time.
Responding to the needs of the epidemic area in a timely manner is not only a simple process of adding modules and functions but also a process of optimization from the clinical operation. However, urgent R&D time makes everything more difficult.
But Zhang Zhuo said that this was actually a good thing because rapid development could test the team's execution and R&D capabilities. The rapid application of iterative products could provide an intensive process for engineers.
In addition to long-term R&D investment, Soundwise Technology cooperates with Stork over the software and hardware coordination, with Stork providing hardware services, and Soundwise providing software support.
"The combination of the two actually exerts the effect of 1+1>2. In fact, this anti-pandemic war also reflects that the software is also a must for handheld ultrasonic instrument to be truly applied in clinical practice."

Stork handheld wireless ultrasound device is easy to use.

Cautions for Using Ultrasound Transducer(2022年)

storkultrasonic — 2022-08-11T12:05:58+0900

https://www.storkultrasonic.com/cautions-for-using-ultrasound-transducer.html

1. Principle of an ultrasound transducer
The most important ultrasonic detection technology is the ultrasound transducer, which transforms the ultrasonic signal into other energy signals (usually electrical signals). The principle of the ultrasound transducer is to use ultrasonic waves for data acquisition. Ultrasonic waves are mechanical waves whose vibration frequency is higher than 20kHz. It has the characteristics of high frequency, short wavelength, small diffraction, and especially good directionality (it can become a ray to transmit in a directional way). The ultrasonic wave has strong penetration into liquid and solid, especially into sunlight-opaque solid. When the ultrasonic wave encounters impurities or interfaces, it will form reflection echoes, and when it encounters a moving object, it will produce the Doppler effect. Therefore, ultrasound transducers are welcomed by medical staff and patients.
The company Stork Ultrasound is one of the most reliable ultrasound probe manufacturers in China. If you are intended to buy a batch of linear probes, convex probes or phased array probes, please contact Stork as soon as possible. High-quality point of care ultrasound machines will fit your needs.

2. Cautions for Using ultrasound transducer
In order to avoid abnormal phenomena in the use of the ultrasound transducer, we should pay attention to the following matters.
1) Do not use the ultrasound transducer outdoors or in places above the rated temperature to ensure its reliability and life;
2) Do not test materials that absorb sounds, such as fine powders and cotton;
3) Do not use nozzles near the ultrasound transducer. The nozzle can emit air jet of different frequencies and affect the ultrasound transducer;
4) The water droplets on the surface of the ultrasound transducer can shorten the detection distance;
5) Do not use an ultrasound transducer near the forced ventilator. The forced ventilator can change local temperatures, and increase the reflection and refraction at the interface;
6) Do not use ultrasound transducers in steam areas. The steam areas have a temperature gradient, which will affect the results;
7) Do not use ultrasound transducer in vacuum area or explosion-proof area.

As one of the portable ultrasound machine manufacturer china, Stork offers app-based imaging system for the handheld portable ultrasound machine so as to provide real-time inspections for professionals.

Application of Handheld Ultrasound in Thyroid and Breast Surgery(2022年)

storkultrasonic — 2022-08-11T12:04:57+0900

https://www.storkultrasonic.com/application-of-handheld-ultrasound-in-thyroid-and-breast-surgery.html

With the continuous development of general surgery, the classification of disciplines continues to increase. One branch of general surgery has been differentiated as thyroid and breast surgery (or gland surgery in some hospitals). Under the current situation, there is a trend for specialization. Therefore, it is more beneficial for professional diagnosis and treatment of diseases to separate thyroid and breast that are belong to general surgery into one department. Also, it is beneficial for patients to have more specialized treatment. It has considerable benefits for both society and patients.

In general, thyroid and breast surgery treat thyroid and breast diseases. Clinically, it mainly solves simple goitre, hyperthyroidism, thyroiditis, thyroid adenoma, thyroid cancer, primary hyperparathyroidism, cervical lymph node tuberculosis, thyroid bone cysts, acute mastitis, breast fibroids, breast ductal tumours, breast papillomas, breast sarcomas, breast cancer, multiple breast cysts, breast hyperplasia and other diseases.

1. Thyroid ultrasound
As one of the endocrine organs, the thyroid is located on the surface of the throat and trachea. It is divided into left and right lobes and isthmus connecting both lobes. The isthmus is located on the surface of the second to fourth tracheal ring, which extends upward to form a hammer lobe. There are individual differences in the weight of the thyroid and is about 25 grams in adults. Compared with females, the position of males' larynx is lower, and the thyroid cartilage protrudes forward, so the position of the thyroid is lower. The anterior cervical muscle group is in front of the thyroid, the sternocleidomastoid muscle is in the front side. The jugular vein and the common carotid artery are on the side of the thyroid, the trachea, esophagus and other organs are on the behind. Also, there is the vagus nerve, recurrent laryngeal nerve, parathyroid gland and other structures around the thyroid. In general, a 7-5~10MHz probe is used for ultrasound examination of the thyroid, and it can be used for color blood flow detection and ultrasound-guided percutaneous biopsy.

A thyroid nodule is the most common endocrine system disease in clinics. In recent years, the prevalence has been increasing year by year. Early detection of lesions and identification of the nature of the lesions are related to the choice of treatment and prognosis for patients. Ultrasonography is the main imaging method for diagnosing thyroid nodules, and it is widely used in the screening and diagnosis of thyroid nodules. Currently, the new ultrasound technology provides more information on the microcirculation and harness of thyroid nodules, which is more important for the diagnosis and differential diagnosis of thyroid nodules.

2. Breast ultrasound
Wireless ultrasound transducers have been used in the examination of breast diseases for more than 50 years. Wild (1951) and other foreign scholars used pulsed A-mode ultrasound to detect breast tissue and breast masses and individual B-mode ultrasound images were obtained. Kossoff G (1972) reported that grey-scale ultrasound can clearly show the breast gland and its pathological features. In the late 1970s, China began to apply real-time ultrasound in clinical ultrasound examinations for breast diseases, which was earliest reported by Xu Guangbo (1979). In the middle and late 1980s, the high frequency linear probe was used to diagnose breast diseases and good results were achieved. Since the 1990s, the application of color blood flow imaging in the diagnosis of breast diseases (especially breast tumors) has been widely reported in the ultrasound field at home and abroad, which has considerable progress in the depth and breadth of the research on ultrasound examination of breast diseases.

The picture shows ultrasound examination of breast tumours
Breast ultrasound was initially used to roughly show the structure of the breast and help distinguish cystic and solid masses. However, with the continuous development of image resolution and computer processing technology, as well as the continuous application of new ultrasound technologies such as contrast-enhanced ultrasound, elasticity, and three-dimensional, ultrasound examination can greatly reflect the fine structure and small lesions in the breast, and ultrasound diagnosis of the breast diseases has become a routine examination method with high sensitivity and specificity.

Ultrasound examination does not bring pain and radiation damage to patients, so it can be used many times in a short period. It is suitable for any age and any physiological period of females, including pregnancy and lactation. Before the inspection, the examinee does not need special preparation. Also, the operation is simple, and there is no blind area for inspecting. Moreover, due to the superficial position of the breast, ultrasound has a good resolution of soft tissues. And it can clearly show each layer of the breast and chest wall, determine the anatomical location and level of the disease, distinguish breast masses and chest wall masses, as well as find a few millimetres of small lumps in the breast. Stork ultrasound can measure the size of breast masses, show the internal structure of breast masses, determine the physical properties of breast masses (cystic, solid, or mixed cystic-solid), and understand the infiltration of breast masses into surrounding tissues. According to the ultrasonography and blood flow signal characteristics, it is helpful to further distinguish the benign and malignant breast masses. For undetermined breast masses, elective ultrasound-guided cytology or core needle biopsy can be used.

Compared with other auxiliary examination methods, ultrasound examination has the advantages of being non-invasive, simple and easy to perform. It can also be used for dynamic observation, and the clinical diagnosis coincidence rate is higher. Therefore, breast ultrasound has been one of the important conventional imaging examination methods in clinical. However, breast ultrasound examination has limitations such as operator dependence, subjective factors, and occult lesions.

Founded in 2016, Stork takes merely four years to become one of the leading handheld ultrasound companies in China.
And we provide different types of ultrasound probes.

Application of Point-of-care Ultrasonography in Trauma Treatment(2022年)

storkultrasonic — 2022-08-11T12:04:24+0900

https://www.storkultrasonic.com/application-of-point-of-care-ultrasonography-in-trauma-treatment.html

Point-of-care ultrasonography (POCUS) has been widely used in trauma treatment. Focused Assessment with Sonography for Trauma (FAST) is a point-of-care examination that allows doctors to quickly evaluate trauma patients and provide support for decision-making. In addition, POCUS has become an important auxiliary tool in trauma surgery, including the establishment of ultrasound-assisted vascular channels and local nerve blocks in anaesthesia, as well as the portability, economy and versatility of ultrasound equipment. Therefore, it becomes a valuable tool for auxiliary examination of trauma treatment in resource-limited environments. POCUS gives hope by playing a clinical diagnostic role in limited-resource environments and pre-hospital settings, and it can provide relevant evidence-based medical evidence for the clinic.

POCUS Examination By Stork Wireless Handheld Ultrasound Scanner
POCUS examination by Stork wireless handheld ultrasound scanner

According to statistics in 2013, there are about 973 million people suffering trauma worldwide each year, and 4.8 million deaths due to trauma. For developing countries with scarce medical resources, the social and economic burden caused by trauma is even greater. Point-of-care ultrasonography (POCUS) examination is a method that uses ultrasound equipment to examine patients at the bedside to provide information to support clinical decision-making. Since the 1990s in the United States, as ultrasound equipment has become smaller and more portable, and the image quality has become higher, the application range is greatly expanded. POCUS machine has great advantages in the treatment of pure and penetrating trauma, especially for trauma patients with hemodynamic instability. These advantages include immediate identification of life-threatening injuries, such as pneumothorax, hemothorax, or pericardial tamponade, as well as assisting with other imaging tests such as plain X-rays or CT scans. In addition, POCUS does not have ionizing radiation so that it allows repeated dynamic assessment of patients.

POCUS Follow-Up By Stork Wireless Handheld Ultrasound Scanner
POCUS Follow-Up By Stork Wireless Handheld Ultrasound Scanner
POCUS follow-up by Stork wireless handheld ultrasound scanner

1. Point-of-care ultrasound machines
The three most commonly used trauma ultrasound probes are curved array probes, linear array probes, and phased array probes. The frequency of the curved array probe is 2~5MHz, and it has strong tissue penetration and is suitable for abdominal cavity imaging. The linear array probe has a higher frequency (7~12MHz) and it can provide better surface structure resolution, display lung apex, blood vessels, nerves, musculoskeletal and other tissues. The phased array probe (1~4MHz) has the smallest volume and can display the heart and thoracic tissue through the auxiliary window. In the case of limited resources, some ultrasound machines do not equip with all three types of probes. However, for trauma assessment, one or two types of probes can basically meet the demand since there are partial overlaps of the inspection windows of these three types of probes. Stork ultrasound can provide you with the following probes.

2. Applications of point-of-care ultrasonography in trauma

2.1 Focussed assessment sonography for trauma
Focussed Assessment Sonography for Trauma (FAST) is a typical POCUS designed to help doctors quickly answer the three core questions in the treatment of patients with blunt or penetrating trauma. Is there a pericardial effusion? Is there free abdominal fluid? Is there a hemothorax? To answer the three questions, the first step is to obtain an ultrasound image at the corresponding part. The most commonly used probe is the curved array probe (2～5MHz).
POCUS -- Few Pleural Effusion
POCUS - few pleural effusion

2.2 Chest wall ultrasound
Although the section of the septum and thoracic cavity is very useful for detecting pleural effusion during the FAST examination, it is difficult to find pneumothorax. Therefore, a separate ultrasound evaluation of the chest wall is required to detect pneumothorax. High-frequency linear probes (7-12MHz) are most commonly used for chest wall ultrasound.

2.3 Enhanced ultrasound
Although two-dimensional ultrasound is very important for the detection of free fluid in the abdomen during trauma, the sensitivity for the identification of intraperitoneal parenchymal organ injury is poor. Contrast-enhanced ultrasound (CEUS) is performed on trauma patients by filling microvesicles and phospholipid shells with intravenous injection of low doses (1.2 to 2.4mL) of emotional gas and then scanning parenchymal organs such as the liver, kidneys, lumbar glands, and organs. After injecting the contrast agent, normal parenchymal organs will show uniformly hyperechoic, while traumatic lesions have relatively hypoechoic due to the reduction of vessel distribution. There is extravasation of microbubbles in the active bleeding. In addition, more and more studies have shown that CEUS has high application value in adults and children with blunt trauma.

2.4 Musculoskeletal ultrasound
The application of ultrasound in the musculoskeletal system began in 1954. Musculoskeletal ultrasound can be used for the non-invasive assessment of soft tissue disease when other imaging tests such as plain X-ray, CT, and MRI are not appropriate or available. Musculoskeletal injuries are more common in patients with single or multiple injuries. High-frequency probes, portable ultrasound machines, and wireless ultrasound transducers facilitate the point-of-care assessment of multiple injury sites, allowing visualization of dynamic operations and complementing physical examinations. The musculoskeletal POCUS can be used to diagnose shoulder dislocation, and POCUS is also a useful tool for assessing tendon injuries, and it also plays a role in assessing fractures.

Knee Joint Ultrasound Guidance By Stork Ultrasound Probe

2.5 Ultrasound-guided local anaesthesia
Delayed administration of analgesics, insufficient doses and insufficient analgesia often occurs in the emergency department. Elderly patients may be more susceptible to this phenomenon than younger patients. The major challenges of analgesia for trauma patients include two aspects. The first is to minimize the time of surgery and invasive operations. The second is the potential adverse effects of systemic analgesia, including respiratory depression, hemodynamic deterioration, excessive sedation and delirium. Ultrasound-guided nerve block anesthesia allows direct observation of self-labeled nerves and surrounding structures. The high-frequency probes can best observe the peripheral nerves.

The Development Prospects of Handheld Ultrasound(2022年)

storkultrasonic — 2022-08-11T12:03:52+0900

https://www.storkultrasonic.com/the-development-prospects-of-handheld-ultrasound.html

The early users of handheld ultrasound were mainly cardiologists, emergency doctors, intensive care personnel and military personnelin the intensive care unit. Emergency medicine is the largest market for handheld ultrasound in 2018, with a scale of approximately US$15 million. However, in recent years, in addition to the continuous expansion of the application of handheld ultrasound in the traditional POCUS market, it has also been widely used in various medical fields (such as urology, gastroenterology, and angiology). Clinicians use handheld ultrasound for rapid inspection and preliminary screening, and use it as an aid to on-board ultrasound.
Relevant studies have shown that so far, the application of handheld ultrasound at the grassroots level has been limited in rural areas. In low-income and middle-income countries, handheld ultrasound helps more patients have access to imaging examinations, mainly for heart screening, pregnancy screening, and diagnosis of respiratory and abdominal diseases.
Primary care is still an untapped market for handheld ultrasound to a large extent, and it may be the biggest opportunity. There are more than 250,000 family doctors in the United States. In the past few years, the price of handheld ultrasound has fallen sharply, and for many family doctors, this is a cost-effective option. With the price drop and the emphasis on ultrasound training for family doctors, the handheld ultrasound will truly be used in the ordinary family. In addition, in February 2020, the US FDA approved the first cardiac ultrasound imaging AI software, which can assist people other than ultrasound doctors in obtaining high-quality cardiac ultrasound images. In the future, handheld ultrasound machine will become a health management tool for everyone.

As one of the portable sonogram manufacturers, we are looking for good partners globally.

Handheld Ultrasound: Puncture Visualization Will Reduce Risk and Increase Efficiency(2022年)

storkultrasonic — 2022-08-11T12:03:25+0900

https://www.storkultrasonic.com/handheld-ultrasound-puncture-visualization-will-reduce-risk-and-increase-efficiency.html

When handheld ultrasound was born, people expected this kind of miniaturized equipment to allow more primary clinics to have low-cost diagnostic tools. In clinical departments, handheld ultrasound plays an important role in intervention, nursing, anesthesia, and intracardiac departments. For the intervention and venipuncture in various clinical departments, the success rate can be improved under the guidance of handheld ultrasound. At the same time, clinicians can help themselves quickly understand the pleural and ascites, lung ultrasound, blood volume, pericardial effusion, etc., to quickly determine the condition.

Interventional radiology is a diagnosis and treatment system closely integrated with imaging diagnosis. It has the distinctive feature of integrating imaging diagnosis and minimally invasive treatment. Interventional radiology refers to the use of puncture needles, guide wires, catheters and other interventional equipment to diagnose and treat diseases under the guidance of medical imaging equipment. It is known as the third largest diagnosis and treatment system after modern clinical therapeutics, after internal medicine and surgery. Interventional radiology has the advantages of minimally invasive, efficient, convenient, safe, and reproducible, which has changed the traditional medical and surgical treatment modes in many aspects. Compared with other clinical departments, interventional doctors are more experienced in imaging diagnosis.
Stork Puncture Enhancement Technology
The introduction of handheld ultrasound equipment combined with DSA and other angiography equipment has improved the combat capability of interventionists. Professor Shao Guoliang, a well-known expert in the field of intervention in the country, made an analogy, "Pistol-style weapons such as handheld ultrasound are simple but practical. For us, one more pistol will solve many problems."

In the interventional puncture guidance link, doctors can use handheld ultrasound to guide the process of suction, puncture, and intubation. If the blind puncture is performed, the doctor needs to have a wealth of experience to complete it. At the same time, blind piercing has certain risks. Accurate puncture under the guidance of handheld ultrasound can avoid multiple punctures. Compared with X-ray guided puncture, ultrasound guided puncture avoids radiation risks for doctors and patients. After many clinical trials, it is found that there are no quality problems in the image resolution and penetration rate of Stork's handheld ultrasound.

Stork's handheld ultrasound GPU architecture plus harmonic images are smooth, with high resolution, and there is almost no delay or lag. During the puncture process, the imaging under the needle ultrasound is very fast and almost synchronized, which greatly improves the success rate.

The frequency of the linear array probe is 4-12 MHz, which can be applied on ultrasonic examination of superficial organs, vessels, and tissues, etc. Compared with other linear probes, Stork linear probes have a more professional algorithm platform and GPU framework to ensure clear images.

Linear array transducers made by Stork Healthcare are used to scan small parts of the body and shallow structures like the thyroid in your neck. The high frequency linear probe produces a more square or rectangular image.
linear probe frequency
The linear array ultrasound probe has a linear arrangement of piezoelectric crystals and good near-field resolution, which can be used for superficial inspection. The frequency of linear ultrasound probes generally used for 2D imaging is 2.5-12MHz. Stork linear ultrasound probe frequency is 4-12MHz, which can be used for various superficial tissues, small organs, peripheral blood vessels, such as blood vessel examination, venipuncture, blood vessel visualization, chest, thyroid, tendon, etc.

Advantages of ultrasound convex probe compared with linear ultrasound probe:

1）The scanning field of the deep part is wider under the condition of equal body surface area.

2）It can effectively avoid the blind angle of scanning caused by the bone tissues such as ribs.

Linear Ultrasound Uses
A linear us probe uses high-frequency ultrasound to create high-resolution images of structures near the body surface. This makes the linear sequential array transducer ideal for vascular imaging and certain procedures such as central line placement.

https://www.storkultrasonic.com/family-care-stork-at-home-ultrasound-machine.html

Family physicians can order a wide range of imaging services for patients. But barriers such as time, money, and physical distance sometimes prevent patients from accessing those services, causing gaps in care. Incorporating point-of-care ultrasound (POCUS) into clinical practice is one way to bridge those gaps.

Technological advancements have allowed more physicians to bring ultrasound services to the office visit or bedside, and to make POCUS ultrasound an integral part of the practice.

There is robust evidence that POCUS improves care in critically ill patients and improves the efficiency and safety of many invasive ambulatory surgeries that are otherwise performed blindly or by anatomic landmarks. There is also preliminary but growing evidence that POCUS can improve diagnostic capabilities, expedite patient care, and inform bedside treatment and management. Most recently, POCUS has proven to be a valuable tool for confirming COVID-19 diagnosis, as well as monitoring some symptoms of the disease.

At home ultrasound machine for pregnancy For COVID-19 Diagnosis
COVID-19 greatly increased the demand for handheld POCUS ultrasound systems

New ultrasound users are driving the growth of the medical point ultrasound (POCUS) market. In order to succeed in the handheld ultrasound market, suppliers need to continue to provide convenience for inexperienced users. Handheld POCUS ultrasound, which combines improved imaging performance, clinical practicability and low price, expands market opportunities outside hospital departments, including office clinical experts. A primary care doctor can equip a very useful diagnostic tool for a surgical operation at a very small cost. This scenario is expected to become the largest medium - and long-term growth driver of this product category.

By 2020, the COVID-19 (SARS-CoV-2) pandemic has greatly increased the demand for a handheld ultrasound. The portable home ultrasound has become a first-line diagnostic tool for coronavirus patients. The availability of affordable and user-friendly handheld scanners helps hospitals process more patients faster - a key factor in an exponentially growing pandemic. Handheld scanners, especially the wireless version, are easier to disinfect than the traditional cart-based system and other imaging methods. Infected patients do not have to go through the hospital to enter the imaging department, which increases the risk of infection transmission. However, it is predicted that the driving force of COVID-19 as handheld ultrasound applications will be weakened because the worst impact of the pandemic (hope) will continue to ease.

The coronavirus pandemic and the subsequent blockade measures implemented by many governments in the world force people to do something at home that used to be done on professional occasions.

In the medical field, the personal family has become a working environment, partly due to the increasing popularity of handheld ultrasonic systems. In these areas, people are scanned at home. Suspected COVID-19 infected people no longer need to go to the crowded emergency room. They can avoid the risk of spreading COVID-19 or avoid being infected by others, provided that they are not infected.

Handheld ultrasonic telemedicine breaks through the distance limit

First, most handheld scanners have built-in presets that can be used to quickly obtain key measurements. For example, the automatic ejection fraction of the heart of the expected due date of the fetus can be calculated automatically by systematic tools.

Secondly, another contributing factor is remote ultrasound, which transmits real-time ultrasound images to experts through the remote conference to guide novice users. During the COVID-19 pandemic, interest in remote ultrasound was strengthened. In addition to a typical remote Ultrasound product, trained professionals can see the scan remotely and talk to untrained professionals through the process. The system superimposes arrows on the user's smartphone to intuitively guide the novice to ensure the correct position of the scanner itself.

Then, AI will also play a key role in helping novices use ultrasound, including AI-supported image capture assistance and automatic anatomical navigation.

Finally, ultrasound probe manufacturer release easy to understand YouTube tutorials that can help consumers learn and use them intuitively. Novices can follow the video to learn how to locate the IQ scanner, the content displayed on the smartphone screen, the settings to press and the specific scanning location.

It is worth mentioning that the coronavirus pandemic and the need to keep people away from hospitals as far as possible mean that it is increasingly possible to carry out more ultrasound tests at home. Initially, it is the responsibility of professionals, but for patients with certain diseases who need to be scanned regularly, they receive handheld devices and basic training at home and then let them scan themselves at a given frequency, and the images are sent directly to the doctor, which may prove safer, more effective and cheaper in the long run.

According to the study of Zanobetti and Scorpiniti, POCUS is a reliable diagnostic method for patients with dyspepsia, which can reduce the diagnostic time. There was no statistically significant difference between the accuracy of POCUS and standard ED in the diagnosis of dyspepsia caused by coronary syndrome, pneumonia, pleural effusion, pericardial effusion, pneumothorax and other reasons; POCUS is more sensitive to the diagnosis of heart failure, while standard ED treatment is better in the diagnosis of chronic obstructive pulmonary disease, asthma and pulmonary embolism.

Portable Home Ultrasound Machine For Pregnancy
Ultrasound is transitioning from the clinical environment to the family environment, which is a new popular trend and has been growing steadily in recent years.

Changes in serum creatinine and/or urine volume during pregnancy or puerperium, POCUS can help to distinguish postrenal and prerenal renal failure. After excluding post-renal causes, the most common cause should consider preeclampsia or eclampsia. POCUS can find renal enlargement and enhanced echo of the renal parenchyma. However, these signs are not unique to preeclampsia and eclampsia, such as acute tubular necrosis or glomerulonephritis. Therefore, it is very important to consider the situation in combination with patients' medical history.

The ultrasonic transducer launched by our company can be connected with smartphones to realize an intelligent experience. The device can not only help pregnant women "enhance the pregnancy experience", but also help pregnant women "understand the health status of their babies". In just a few years, at home ultrasound has changed from a clinical tool to a technology. Theoretically, it can be used by anyone at any time and anywhere.

Common Types Of Ultrasonic Probes(2022年05月13日)

storkultrasonic — 2022-05-12T18:16:07+0900

https://www.storkultrasonic.com/common-types-of-ultrasonic-probes.html

An ultrasonic sensor or a probe generates sound waves, and the reflections of the sound waves produce clear images of body tissues and organs, which is an important part of the ultrasound system. The following are the three most common ultrasonic probes types:

Linear ultrasound probe

As the name suggests, there is a linear piezoelectric structure. The beam shape is rectangular, and the near-field resolution is higher than average. Depending on the clinical application, the frequency, footprint, and application of the linear probe are likely to vary.

The linear ultrasound probe used for 2D imaging has a wide coverage range, and its broadband frequency is 5-20 MHz. The high frequency linear probe is used to examine the breast, thyroid, tendons and blood vessels, and to measure the thickness of carotid artery disease.

Convex ultrasound probe

The convex array probe is also commonly called a curved probe, there is a curved piezoelectric crystal arrangement, and the beam is convex.

The probe used for 2D imaging has a wide coverage range, and its broadband frequency is about 2.5 MHz-7.5 MHz, which can be used for abdominal and vaginal examinations.

The probe used for 3D imaging has a wide field of view, and its broadband frequency is 3.5 MHz-6.5 MHz. 3D bending probes usually use electromechanical moving parts in the head, and are usually used to diagnose pregnancy abnormalities.

Phased array ultrasound probe

The phased array ultrasound probe is so named because the crystals are arranged in a "stacked" structure. The beam is very narrow, close to a triangle, and the near-field resolution is poor. This kind of probe has a small footprint and a broadband frequency of 2-6 MHz. It is mainly used for cardiac and transcranial examinations.

Other types of ultrasound probes

Such as the pencil type, intracavity type and transesophageal type, all have a specific purpose: to check blood flow, internal cavity and heart respectively. Some probes, such as laparoscopic probes, are specifically designed for surgical procedures.

Principle of the Medical USG Transducer(2022年01月24日)

storkultrasonic — 2021-12-28T11:23:44+0900

https://www.storkultrasonic.com/principle-of-the-medical-usg-transducer.html

1. What is the medical USG transducer

The medical USG transducer can be regarded as a set of information conversion device, which can convert the physiological information of the human body into electrical information with a definite functional relationship. It contains a very comprehensive science and technology.

2.Principle of the medical USG transducer

Human physiological information is divided into two categories of electrical information and non-electrical information. In terms of distribution, there is internal information (such as blood pressure and other types of pressure), body surface information (such as electrocardiogram and other types of bio-electricity) and external information (such as infrared, biomagnetism). The medical USG transducer is a device that converts the change of physical quantities (mechanical quantities, mechanical quantities, etc.) into electrical quantities. In general, it is composed of elastic elements, sensing elements and measuring circuits. The elastic element is the bridge that connects the measured object and the sensing element, and it is the key component of the medical USG transducer. The structural shape, material, processing accuracy, heat treatment technology, etc. will affect the performance of the transducer. The processing technology of the elastic element has a great influence on the performance of the medical USG transducer. In general, it should be processed by heat treatment after rough machining, and then processed by special aging treatment. Also, static and dynamic loading treatments can be carried out after reducing mechanical hysteresis in order to improve elasticity.

In terms of structure, it is required that the elastic element is only affected by the measured physical quantity while minimizing the influence of other physical quantities as far as possible. The material of the elastic element should have high strength and toughness, good elasticity, low hysteresis, high fatigue limit, and good hardenability. According to the force and deformation, the shape of the elastic element can be divided into cantilever beam, simply supported beam, pure bending type, tension and compression rod, hollow circular shaft, etc. Different forms can be selected for different purposes. The medical USG transducer is the product of the continuous development and combination of medical biomedical technology and engineering technology.

Principle of Ultrasonic Probe(2022年01月18日)

storkultrasonic — 2021-12-28T11:23:13+0900

https://www.storkultrasonic.com/principle-of-ultrasonic-probe.html

Ultrasonic probe is a device that transmits and receives ultrasonic waves during the ultrasonic detection process. The performance of the probe directly affects the characteristics of the ultrasonic, and affects the detection performance of the ultrasonic. The key component in the probe is the wafer. The wafer is a single crystal or polycrystalline sheet with piezoelectric effect. Its function is to convert electrical energy and sound energy to each other.

1. The principle of ultrasonic probe

Ultrasonic probes mainly use the inverse piezoelectric effect of piezoelectric crystals such as quartz to complete the conversion of electrical energy to ultrasonic mechanical vibration (ie, the emission of ultrasonic waves), and use the piezoelectric effect of piezoelectric crystals to complete the conversion of ultrasonic mechanical vibration to electrical energy (ie, ultrasonic reception). Therefore, the ultrasonic probe can be called an ultrasonic generator or an ultrasonic receiver. It is an important part of ultrasonic testing and an important structure that affects the test results.

2. The key components of the ultrasonic probe

The ultrasonic probe is equipped with two chip probes, one of which is as a transmitter and the other as a receiver. The dual crystal probe of the ultrasonic probe is mainly composed of a socket, a shell, a sound insulation layer, a transmitting chip, a receiving chip, a delay block, etc., and a vertical longitudinal wave sound beam is used to scan the workpiece. The dual crystal straight probe has better detection ability of near-surface defects; for rough or curved inspection surfaces, it has better coupling effect, and is used in semi-automatic or automated flaw detection systems. When the axis of the sound beam emitted by the ultrasonic probe is perpendicular to the detection surface, the longitudinal wave direct sound beam scans the workpiece; adjust the probe sound beam axis to form a certain angle with the detection surface, and the sound beam is refracted at the interface between the water and the workpiece. The inclined transverse wave sound beam can be generated in the workpiece to scan the workpiece. When the plexiglass or cured epoxy resin in front of the ultrasonic probe wafer is processed into a certain arc, a point-focused or line-focused water immersion probe can be obtained.

Structural Analysis of Sonography Probe(2022年01月17日)

storkultrasonic — 2021-12-28T11:22:37+0900

https://www.storkultrasonic.com/structural-analysis-of-sonography-probe.html

1. Overview sonography probe

Sonography probe is an important part of ultrasonic testing, and it is also an important structure that affects the test results. As a precision instrument, sonography probes are used frequently in clinical ultrasound examinations and directly contact human skin and mucous membranes. Therefore, it is necessary to understand the structure of the sonography probe and protect it from damage as much as possible.

2. The structure of the ultrasound probe

Sonography probes are divided into in-vivo probes and in-vitro probes according to the application method. Among them, in vivo probes include intravascular probes, female probes, rectal probes and transesophageal probes. Extracorporeal probes can be divided into cardiac probes, abdominal probes and thyroid probes. The sonography probe is a precision instrument, and the parts from the outside to the inside: acoustic lens, matching layer, wafer, sound absorption block, support frame and sound head shell. Among them, the chip is the core part, which is a high-energy sensor, which has the function of transmitting and receiving sound waves. The acoustic lens concentrates the light waves emitted by the wafer, which can improve the ultrasonic resolution. If the outermost acoustic lens is damaged or rubbed hard, the penetrating power of the acoustic lens will decrease, leading to its damage and affecting the diagnosis result.

Because of the particularity of the material of the sonography probe, most of the sonography probes cannot be disinfected by ordinary disinfection methods such as ultraviolet radiation, 75% alcohol, aldehydes, oxidants, etc. If the disinfection method is improper, it will also affect the diagnosis results, and may even damage the service life of the probe. The structure of the sonography probe is not watertight. Once liquid enters the sonography probe, it may cause a short circuit of the internal materials, which may cause the diagnostic system to fail to work properly. Therefore, no liquid is allowed to submerge the seam line under the sonography probe.

Stork is a professional ultrasound probe manufacturer, we provide best handheld ultrasound devices, transducer probe, handheld ultrasound probe, etc.

Knowledge About Medical Sonography Probe(2022年01月04日)

storkultrasonic — 2021-12-28T11:20:51+0900

https://www.storkultrasonic.com/knowledge-about-medical-sonography-probe.html

1. The piezoelectric effect of sonography probes
The sonography probe is an indispensable key part of the ultrasonic diagnostic equipment. The sonography probe can not only transform the electric signal into an ultrasound signal, but also transform the ultrasound signal into an electric signal, that is, it has the dual functions of ultrasound transmission and reception.

The core of sonography probe is piezoelectric crystal or composite piezoelectric material. The transducer used in the early ultrasonic probe is a crystal with piezoelectric effect. Using high molecular polymer piezoelectric material as the transducer, it has the characteristics of frequency bandwidth, low impedance, softness and easy processing.

The current sonography probe has begun to use composite materials composed of ceramics and high molecular polymers. There are some special crystals in nature. When they are deformed by external force, they will generate electric charges on the surface of the crystal to form a voltage. This effect is called piezoelectric effect, and this kind of crystal is called piezoelectric crystal.

2. Medical piezoelectric materials for sonography probes

The piezoelectric crystal (vibrator) is the core component of the ultrasonic transducer. Piezoelectric crystals can be divided into natural and artificial. Quartz crystal is a natural piezoelectric material, but it is expensive and the performance index is not consistent. The piezoelectric materials currently used are basically artificial piezoelectric crystals.

The structure and type of the medical sonography probe, as well as the conditions of the external excitation pulse parameters, working and focusing methods, have a great relationship with the shape of the ultrasound beam it emits, and also have a great relationship with the performance, function and quality of the ultrasound diagnostic apparatus. The transducer array element material has little relationship with the shape of the ultrasonic beam; however, the piezoelectric efficiency, sound pressure, sound intensity and imaging quality of its transmission and reception have a greater relationship.

Application of the Wireless Ultrasound Transducer in Medical Treatment(2022年01月03日)

storkultrasonic — 2021-12-28T11:19:58+0900

https://www.storkultrasonic.com/application-of-the-wireless-ultrasound-transducer-in-medical-treatment.html

1.Introduction of the wireless ultrasound transducer

The ultrasonic waves emitted by the wireless ultrasound transducer are also known as mechanical waves, which have good directionality, strong penetrating ability, and the ability to spread in water and air. The wireless ultrasonic transducer can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, disinfection, etc. Based on the vibration excitation mode, transducers commonly used in ultrasound can be divided into magnetostrictive transducers and electrostrictive transducers.

At the beginning of the 20th century, the development of electronics enabled people to make various electromechanical transducers by using the piezoelectric effect and magnetostrictive effect of certain materials. In 1917, people made sandwich-type ultrasonic transducers with natural piezoelectric quartz and used them to explore submarines on the seabed. With the continuous development of ultrasonic applications in various military and economic sectors, magnetostrictive transducers with greater ultrasonic power have emerged, as well as various types of ultrasonic transducers with different purposes such as electric, electromagnetic, and electrostatic transducers.

2. Application of the wireless ultrasound transducer in medical treatment

The application of the wireless ultrasound transducer in medical treatment is mainly divided into medical testing and medical treatment.

As you commonly see in hospitals, medical instruments that we can commonly see such as B-ultrasound, color doppler ultrasound, ultrasonic holography technology, ultrasound scalpel, and ultrasound crushing technology all use the wireless ultrasound transducer to work. The working principle of medical ultrasound is similar to that of sonar. When the ultrasonic wave emitted into the human body will be reflected and refracted when they encounter interfaces, and it will be absorbed and attenuated by the human body so that there is no harm to human body tissues. The wireless ultrasound transducer is used in different medical devices with different purposes. Also, the wireless ultrasound transducer is widely used in the medical industry because it is not harmful to the human body.
