Abstract
The definition diaphragm for the X-ray beam located at the image receiver serves to eliminate part of the stray radiation. According to the invention, the diaphragm comprises a frame and a plurality of partial overlap members each having one portion made from lead rubber, so that it can be turned down perpendicular to the plane of the opening, so that the radial dimensions of the diaphragm are reduced to a minimum. Application is to conventional radiology.
