ABSTRACT:
The apparatus for non-contacting disintegration of concretions situated in a life form includes a patient bed, a shock wave generator secured on a carriage below the surface of the bed with an arrangement for coupling energy from the shock wave generator positioned between the generator and the bed; an X-ray unit being mounted for pivotable movement on a longitudinal axis and used for positioning the patient with the isocenter of the region to be treated to lie on the longitudinal axis at a space above the surface of the bed and the carriage for the shock wave generator moving the focal point of the shock wave generator along said longitudinal axis from a working position with the energy focused on the isocenter to a remote position. The arrangement for mounting the X-ray unit includes a C-shaped carrier, which will pivot around the longitudinal axis and positions the X-ray radiator or emitter on an opposite side from the radiation receiver. In addition, the apparatus will pivot the shock wave generator around the same longitudinal axis and the C-shaped carrier is preferably pivotable around a second axis perpendicular to the longitudinal axis.
