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

The maximum sound pressure and the rising temperature is produced by the two sound sources differ greatly, but the ratio of the maximum temperature rise to the maximum sound absorptivity is almost the same.High intensity focused piezoelectric ceramic is indicating that the efficiency of the absorpti

Considering the basic requirements of real-time imaging of tumor treatment ,It includes compatibility considerations and cost control requirements of the ultrasound therapy machine itself, the domestic commercial HIFU piezo ceramic ultrasound tumor treatment machine has selected B-ultrasound as for

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
