We designed the three-dimensional spherical array of geometric model-spherical crown array model. In other words, using the adjacent triangles as the modeling material, a finite shape is established.A geometric model of a spherical crown array is composed of planar regular hexagonal elements of the

In the process of designing the probe structure, researchers often use probes such as field .it is structural design software for diagnostics, or the design of therapeutic probes. However, because of the two softwares, the algorithm for calculating the sound field is time-complex. In the design of t

In the manufacturer of piezoelectric ceramic sheets, the fabrication cost of a large-aperture curved self-focusing piezoelectric ceramic sheet can be up to 10000 yuan. The manufacturing of a single chip small-area planar piezoelectric ceramic requires only tens of dollars to several hundred yuan. An

People try to optimize the probe's array design parameters (such as array elements, array elements, etc.), optimizing the acoustic matching components of the probe, array element shape, size, fill rate, optimize the sound field meter for probe design and calculation method, optimizing. The signal mo

In the field of cancer treatment, high-intensity focused ultrasound HIFU tumor treatment technology is the fourth new tumor treatment technology after surgery, chemotherapy and radiotherapy. The common HIFU piezo ceramic in the clinic is to use the ultrasonic medium to radiate energy to the tumor si

For a multivariate linear array transducer with Zn+1 array elements, if all the array elements emit sound waves at the same time,Let the sound pressure value of the array element at point F be p: then the total sound pressure of point F value is: pSince the distances of the respective line elements

Mechanical sector scanning is performed by a motor driven by a single or multiple piston transducers around a fixed axis or a scanning system formed by rotation. Usually the transducer is placed in a container filled with liquid, the entire system is close to keep contact with the surface of the hum

Ultrasound focusing piezo ceramic is not only important ultrasound surgery, but also ultrasound diagnostics. people always want to see smaller, more subtle organizational structures, such as the internal organization of the internal organs of the human body, eyes and skin, etc., not only to increase

The use of ultrasound HIFU piezo ceramic for diagnosis and treatment has become one of the most important branches of medical bioengineering.More and more people are paying attention. As early as the 1930s, there were reports of ultrasound for treatment after forty years.Generations have proposed th

In recent several decades,ultrasonic phased arrays had been applied to many medical specialties and nondestructive evaluation(NDE).An ultrasonic phased array consists of multiple Hifu piezo transducer impedance which are usually cut or etched from a single piezoelectric plate of lead zirconate tina

HIFU uses secondary HIFU piezo ceramic technology to transmit ultrasonic waves from multiple probes to outside the patient's body, and focuses of the lesion to form a high-intensity focal spot similar to the size of rice. Producing high temperature to burn cancer cells. For the purpose of treatment,

Almost all methods must measure the acoustic characteristics of various tissues and their temperature characteristics, and these parameters usually vary from tissue to tissue, which brings difficulties in ultrasonic non-destructive temperature measurement technology. This is an urgent need to solve

With the continuous development of computer technology, computers have become an indispensable control for ultrasonic high focus piezoelectric treatment systems. In the actual treatment process, the target should be tracked and monitored in the real time through the computer! The target is compared

The planetary deceleration technology can make the precision of scanning reach 0.01mm, and then use the medium and high grade B-ultrasound and Hifu piezoelectric crystal treatment system to form IC parts, it guides the positioning and target tissue, and implement the monitoring effect. For the first
