Abstract
Disclosed is a radiology system of the mammograph type in which there is provision for a radiation controller. The invention lies in the fact that the input aperture of the detector is masked by a belt that absorbs the X-radiation except at zones, the variable dimensions of which are designed to get adapted to the different shapes of breasts. The belt is driven by a motor 24 and stops at the practitioner's command so that the appropriate zone is in correspondence with the input aperture of the detector 22.
