摘要： 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.

摘要： An X-ray radiology device comprising a rotating and flat lift. For this X-ray device to operate correctly, it is necessary to obtain and maintain, for all the incidence angles, a perfect alignment of the focal point of the X-ray tube, the element observed and the detector. This geometric imperative is achieved in one embodiment by means of a compensation system. The compensation system includes a cam fitted to a free end of the lift. The compensation system includes a lever in contact with the profile of the cam. The lever is in contact with the detector or the tube connected to the lift. Thus, when the lift rotates, the cam pushes the lever, which in return pushes the tube or the detector in order to align it.
