Abstract

A targeting device for x-ray locating during an extracorporeal treatment of patients with focused shock waves, particularly for a lithotritor, is suggested. The targeting device comprises a carrier on or in which x-ray positive elements, preferably metal wires, are arranged such that they point to the focal point of the shock wave system. In the x-ray image, the position of the elements clearly indicates the position of the focal point.
