ABSTRACT:
A lithotripsy work station has a patient support table which is adjustable in three dimensions by a position control unit. The support table has an opening therein through which a shock wave generator can be coupled to a patient on the support table for disintegrating calculi in the body of the patient. An x-ray system is provided for identifying the position of the calculi within the patient, and a video chain is connected to the output of the x-ray system for providing a visual display of the calculi within the patient. A unit is connected to the table control unit which identifies the current position of the support table, and an arithmetic unit calculates the limits of the area or range within which the shock wave generator can be effectively coupled to the patient, given a particular table position. A video signal generator generates a video signal from the output of the arithmetic unit which is mixed with the patient image on the display, providing a visual representation of the range limits on the display screen.
