Abstract: The therapy apparatus described for treating concretions and tissue in the body of a patient by means of sound waves comprises a sound wave generator and an available X-ray device for locating an object for therapy, wherein the therapy apparatus has a spot film device. The spot film device is arranged within the axial passage of an X-ray cone for the available X-ray device attached to the sound wave generator and with its central longitudinal axis aligned with the focus thereof to be able to precisely adjust and fix a known X-ray device available to the therapy apparatus relative to the therapy apparatus quickly and safely.

Abstract: An apparatus for shock wave treatment includes a shock wave transducer with a cup-shaped body and with an X-ray location finding device for finding the location of a bodily concretion or tissue to be treated. The X-ray device includes an extensible X-ray tube with telescoping tube sections which are sealed against an acoustic coupling medium filling the delay path of the transducer by a balloon arranged within the X-ray tube. The balloon is secured to the upper section of the tube and to the lower section thereof. Overpressure or underpressure is applied to the interior of the X-ray tube to adjust its length in order to optimise X-ray location finding on the one hand, and shock wave treatment on the other hand.
