Piezoelectric ceramic hemisphere  

Electrode direction: thickness direction


Applications:  High Intensity Focused Ultrasound, Ultrasonic Transducer


Ultrasound focusing is the use of ultrasound as a source of energy. A lot of ultrasound beams are emitted from outside to the body. During the transmission process, they focus on one point, that is, tumors. Through the transformation of sound wave and heat energy, a high temperature treatment point of 70 100 is formed in 0.5 1 seconds. This high temperature point is like a scalpel cutting tumors, and tumors in the focus area are unavoidable. Ultrasound focusing knife can cause coagulative necrosis of tumor tissue and loss the ability of proliferation, invasion and metastasis. The principle of this machine is similar to that of a solar cooker, which concentrates sunlight at the focal point and generates tremendous energy.
