Abstract: A stretcher with a dedicated multi-functional removable floating patient support platform is described. The stretcher has a lower frame assembly and an upper frame assembly is vertically displaceable thereover in an adjustable manner. The patient support platform is a rigid rectangular platform having a substantial portion thereof constructed of radiolucent material. The patient support platform is supported on bearings and retained captive on a platform support structure, whereby to slide axially thereof. Restraining hingeable side frames are provided and permit the patient support platform to be displaced laterally on the bearings to permit the patient support platform to be transferred from the platform support structure laterally thereof, in an effortless support manner.

Abstract: The device is used for compensating a hyper transparency area due to air inside or outside an organ while using a gantry mounting radiography apparatus with digital subtraction (DSA). The device comprises compensating filters and a supporting assembly for connecting the filters in front of the X-ray source. Each filter extends in a filter plane while the organ defines a median plane in which the rotation axis of the arms of the apparatus is substantially lying. The supporting assembly is designed to keep the filter in front of the X-ray source and in registry with the X-ray source and the hyper transparency area while keeping the filter plane parallel to the reference plane during rotation of the arms. Unlike existing X-ray compensating devices which are stationary, the present invention automatically sets itself for radiography of different views in function of the rotation of the arms of the apparatus.
