ABSTRACT:
An extracorporeal lithotriptor has a shock wave head which includes a shock wave generator which generates shock waves to disintegrate calculi in situ, and components for coupling the generated shock wave to the patient. The lithotriptor also includes an x-ray system for locating a calculus to be disintegrated. The x-radiator for the x-ray system and the shock wave head are arranged relative to each other so that a central x-ray of the x-ray system proceeds substantially centrally through the shock wave head. The shock wave head can be arranged either at the housing of the primary radiation diaphragm for the x-ray system, or in front of the input luminescent screen of an x-ray image intensifier. The shock wave head has a central region which is penetrated by x-rays and which does not attenuate the x-rays.
