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

Medical ultrasound transducer can be divided into diagnostic ultrasound and therapeutic ultrasound. Diagnostic ultrasound is ultrasonic frequency of 1 to 10 MHz.The low-energy form is applied to the clinic, mainly for the purpose of extracting biological information, and Pzt material stripe piezo ce

A new type two-dimensional spherical crown array is designed. Based on the self-built sound field platform, the sound field characteristics of the model are studied. Finally, the structure characteristic parameters F-number, arrangement and other structures of the array are found. The characteristic

For the multi-array dome array of HIFU piezo ceramics, the different array arrangement means that the array has different structural characteristics, and different structural characteristics will correspond to different array sound field characteristics, such as the same focus , different focal leng

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.
