Taking the simulation model of HIFU for breast tumor as a reference, establishing the additional transducer as shown in the figure .A three-dimensional simulation model of human body is fat or muscle tissue with a certain angle of sound, and is carried out in three dimensions simulation calculation,

At present, the methods for studying the sound field of HIFU piezo ceramic mainly include experimental measurement methods and numerical simulation methods.The methods for measuring high-intensity ultrasonic sound fields are mainly hydrophones, ultrasonic radiation balances and fiber optic sensors.t

The multi-spherical crown HIFU piezo ceramic treatment probe is a complex structure. When is designing the probe, We need to determine a lot of design parameters, including the number of array elements, the arrangement of array elements, the frequency,The array size and the radius of curvature of th

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

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
