Abstract
An apparatus for X-ray examination is used for so-called mammagraphic work. It includes an X-ray tube, a supporting surface for the exposure material and a compressing device. The invention is particularly characterized in that a constant distance is maintained between the X-ray tube and the supporting surface for the exposure material and in that the compressing device is adjustable independently from the X-ray tube and/or the supporting surface. By way of example, the compressing device may be a compression tube supported so as to be movable in the direction toward the supporting surface.
