Abstract: A filtering system for use in, for example, a radiological imaging in a mammography apparatus. The system has a roundabout carrying a set of filtration plates. Each filtration plate is held on the roundabout by a joint. In a parked or stationary position, each plate is vertically suspended and does not contribute to any unacceptable increase in the horizontal space requirement of an X-ray tube. Each filtration plate may be presented in turn before a window for the emission of X-rays from the tube. At this position, the plate is rectified about its joint in order to occupy one position, among several possible positions, that also makes it possible, in this way, to modulate the filtration capacity of the plate.

Abstract: An X-ray apparatus has hollow motors providing hinge joints for a mobile part in rotation relative to a reference part. Each of the motors includes a rotor fixed to the mobile part as well as a stator fixed to the reference part. The axis of these motors is indistinguishable from the axis around which the mobile part can go into rotation. The motors facilitate an assembling of the parts of the apparatus in permitting cables or wires to cross through the hollow motors. The hinge joints provide a direct transmission between the mobile and reference parts.
