Abstract

A lithotripter includes a therapeutic head provided with a source for focusing shockwaves in a focal point on a first axis; an ultrasonic transducer having an axis for imaging an area in a patient in which shockwaves are to be focussed is connected to the therapeutic head for movement in relation to the head in isocentric relation to that focal point such that two axes intersect in that focal point, independently form a variable angular orientation of the axes to each other.
