ABSTRACT:
An apparatus for destroying concretions in an object or an organism, has a device (300) for the emission of waves, which is arranged outside said object or organism, and for focussing these waves onto the location of concretions which are localized by means of a localization device. The localization device has a fluoroscopy assembly (100) for determining an axis S.sub.1 L.sub.1 of the location of the concretion to be destroyed, and an assembly (200) for detecting photons diffused transversely of said location axis. The fluoroscopy assembly (100) has an X-ray source (101) and a diaphragm (111) as well as a system (102) for the processing of signals and the calculation of coordinates. The assembly (200) for the detection of diffused photons includes a photon detector and an electronic circuit (204) for counting, the detected scintillations.
