ABSTRACT:
A lithotripsy work station for disintegrating a calculus in a patient has a patient support table on which the patient is disposed, a drive unit for selectively positioning the table, a shock wave generator, an x-ray system for generating a three dimensional visual representation of at least the region of the patient in which the calculus is disposed. The location of the focus of the shock wave generator is known with respect to the x-ray representation. A mark generator generates at least one mark superimposed on the x-ray representation, and also generates a signal which is supplied to the drive unit which causes the drive unit to position the table based on the position of the mark on the x-ray representation with respect to the position of the focus. A mark positioner is also provided for manually positioning the mark on the x-ray representation in coincidence with the calculus, so that the table is moved to a position with the patient thereon such that the focus coincides with the calculus for effective disintegration or shattering thereof.
