Effect of the diameter and the sound speed of a kidney stone on the acoustic field induced by shock waves

Abstract:

A time-domain finite-difference solution to the acoustic wave equation was used to model the propagation of lithotripsy shock waves in kidney stones. Varying the sound-speed of the stone had minimal effect on the pressure within the stone. Reducing stone diameter dramatically reduced negative, but not positive, pressures. For composite stones the pressures amplitude changed little, but specific configurations resulted in the peak negative pressure occurring at an internal interface - a likely...
