ABSTRACT:
A lithotriptor station has a shockwave generator connected to a drive circuit and an x-ray system for generating an image of the calculi to be disintegrated. An output of the x-ray system is applied to a detection circuit which forms an electrical signal corresponding to the degree of calculus disintegration in the x-ray image. The electrical signal is supplied through a computer to the drive circuit for the shockwave generator for controlling the number of shockwaves administered.
