Abstract
Biopsy assembly for use in an x-ray examination apparatus having an x-radiator with a focus from which a ray pyramid emanates, and a radiation receiver arranged residing opposite the x-radiator for producing an x-ray picture of an examination subject situated between the two, the biopsy assembly determining a paracentesis point of a biopsy needle pertaining to a diagnostically relelvant region imaged on the x-ray picture and situated inside the examination subject and positioning the biopsy needle relative thereto. The biopsy assembly includes a guide element having a channel for the biopsy needle with a diameter essentially corresponding to that of the biopsy needle, and a positioning system for adjusting the guide element relative to the region of the examination subject such that the longitudinal axis of the channel of the guide element always proceeds through the focus of the x-radiator.
