1.Applications in medical and beauty products.Ultrasonic beauty is generated a high frequency alternating current by generator , which make the piezoelectric chip to generate ultrasonic waves. It mainly uses the mechanism of ultrasonic waves on human skin and superficial tissues. In the medical, 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

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

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

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

With the development of science and technology, the non-destructive testing technology of temperature field has made great progress, and some non-destructive side temperature methods of HIFU piezo ceramic have been proposed.Such as electrical impedance tomography, magnetic resonance (M IR) ultrasoun

With the development of HIFU piezo ceramic technology, the HIFU technology has attracted great attention on the engineering and medical circles. Many units in China have carried out research and development and clinical application of HIFU equipment, and have achieved remarkable results. this paper

In order to realize the HIFU ultrasound piezo, the traditional methods mostly use a single frequency ultrasonic transducer, and the use of the same focusing system to achieve the focus of the two frequency ultrasound is rarely reported. In 1996, Japanese scholar S. Umemura et al. studied a technique

In recent years, the application of HIFU piezo transducer ultrasound in the field of tumor treatment has been widely concerned at home and abroad. It has been reported that nearly 10 domestic manufacturers have invested a lot of manpower and resources to develop in the clinical applications in the m

High intensity focused ultrasound(HIFU)technology asa non is an invasive treatment way that have been used in tumor disease,which will make the ultrasound piezo be in the target region under the thermal effects,cavitation effects and mechanical effects of ultrasound .The lesions could be destroyed
