HIFU piezo ceramic technology as a new clinical treatment method, mainly including extracorporeal shock wave lithotripsy (ESWL)therapy, HIFU tumor treatment and extracorporeal shock wave lithotripsy (ESWL) treatment technology. Extracorporeal shock wave lithotripsy is the use of ultrasound or lo

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

Multi-array HIFU piezo ceramic ultrasound transducers can also be divided into two types, one is pure multi-array form, and the other is multi-phase phased array focusing. A pure multi-array element generally places a plurality of piezoelectric ceramic sheets in the concave spherical surface of seve

HIFU piezo for ultrasonc knife has the outstanding advantages of no pain, no surgery, short side effects, short treatment and recovery time, which has become a hot spot in the research of tumor treatment equipment. However, due to its therapeutic effect, it has yet to be extensively clinically teste
