An experimental lithotripsy system for the study of shock wave effects
The authors have developed a lithotripsy system and measurement set-up for the study of shock wave interaction with living tissues. The system consists of an electromagnetical shock wave generator, focusing lens and capacitance pressure pulse measuring hydro-phones. The shock wave pulse pressures obtained with this system can be changed up to 40 MPa (about 400 atm). An additional ultrasonic system enables measurements of the gas bubbles generation, an important factor in the destruction process caused by cavitation. Details of the system concerning the shock wave generation, pressure field distribution, pressure time dependence and measurement technique as well as its practical application possibilities are discussed in the paper.
