Study on Enhancement Effect of Cavitation Caused by HIFU Piezoelectricity Transducer

摘要

HIFU with frequency at 1.05 MHz combined with ultrasound with frequency at 28 kHz was applied in this paper. Effect of cavitation was detected by pH-value measurement and conductance measurement. The result shows that effect of cavitation caused by ultrasound with frequency at 28 kHz was greatly enhanced by HIFU piezoelectricity transducer with frequency at 1.05 MHz.
