Device for optical control of the coupling quality between a shock wave head of a lithotripter, and the surface of the body of a patient

摘要

A device for optical control of the coupling good between a shock wave head (2) of a lithotripter, and the body surface of a flat of a patient (12) comprises a picture-taking unit (14) for receiving a a between the patient (12) and of the coupling member flat (8) of a koppelbalges (6) coupling layer (10) located in at least one coupling region (20) reproducing image, a position detection of a unit for determining the position or the position and shape of the coupling region (20) as well as a control means (40) for controlling the picture-taking unit (14) as a function of the position or from the position and shape of the coupling region (20).
