ABSTRACT:
The focus of a lithotriptor comprising a transducer for generating focused ultrasonic shock waves is adapted for alignment on a concretion or tissue to be destroyed. The transducer is connected to an image-forming diagnostic X-ray system for locating the concretion or tissue, and comprising an X-ray emitter and an image intensifier disposed on a pivotable frame. The transducer is connected to the X-ray emitter, and the X-ray emitter is disposed at the center of the transducer, so that the emission axes of the transducer and the X-ray emitter coincide.
