ABSTRACT:
A shock wave source for use in lithotripsy has an electromagnetic shock wave source with the ultrasound head of an ultrasound locating system centrally disposed within the source. During locating of a calculus to be disintegrated, at least one surface normal of the exit face of the ultrasound head is aligned obliquely relative to the surface normal of the coupling surface of the shock wave source. Image disturbances due to multiple echoes are avoided by the oblique positioning of the ultrasound exit face.
