With the continuous development of computer technology, computers have become an indispensable control for ultrasonic high focus piezoelectric treatment systems. In the actual treatment process, the target should be tracked and monitored in the real time through the computer! The target is compared

The planetary deceleration technology can make the precision of scanning reach 0.01mm, and then use the medium and high grade B-ultrasound and Hifu piezoelectric crystal treatment system to form IC parts, it guides the positioning and target tissue, and implement the monitoring effect. For the first

With the development of science and technology, the non-destructive testing technology of temperature field has made great progress, and some non-destructive side temperature methods of HIFU piezo ceramic have been proposed.Such as electrical impedance tomography, magnetic resonance (M IR) ultrasoun
