  • Patent number: 5263076
    Abstract: A lithotripsy workstation, comprises a patient supporting device (1), a shockwave source (4) for generating shockwaves which are focused onto a point (focus) (6) fixed in space, an X-ray source (10) which irradiates the focus (6) from at least two defined positions, and an image detector (12) which detects the X-ray image produced by the X-ray source (10). The cost and the weight of the workstation can be reduced in that a marker (16) which can be displayed in the X-ray image is secured to the X-ray source (10), which marker is situated, at least in the two positions, on the connecting line between the focal spot (11) of the X-ray source (10) and the focus (6).
