Analysis of Vibration and Its Break Efficiency Due to Focal Position Induced by Piezoelectric Extracorporeal Shock Wave Lithotripter

압전식 ESWL장치를 사용한 대상물 진동시 초점위치에 따른 진동 및 파쇄효율의 분석

In this paper, the relation between the vibration and the sound radiated due to the piezoelectric ESWL (Extra-corporeal Shock Wave Lithotripter) is examined And the relation between the focus and the vibration of the objects is examined. The same experiments with the objects that can be breton are done and the relation between the vibration and the break efficiency of the phantom is experimentally investigated. These results show that the relativity between the power of the peak frequency and the break efficiency can be confirmed.
