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 designing parameters of the HIFU piezo ceramic directly affect the performance and production cost of the system. This paper is based on the existing hardware foundation of the laboratory, based on the spherical crown ultrasonic array model, the basic design of the probe parameters is proposed.

In order to achieve quantitative analysis of the sound field characteristics of the HIFU piezo ceramic treatment probe in the single focus scanning mode, The following three key acoustic field characteristics are studied.

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

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

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,
