Abstract
In an exemplary embodiment displaceable clamping jaws mount x-ray film cassettes of varying format for movement into the exposure position. In the case of such x-ray cassette changers it is necessary that the width-definition of the cone of rays corresponds to the dimensions of the inserted x-ray film cassette. The film support, in the case of fluoroscopy, should be capable of being removed from the examination apparatus without difficulties. For this purpose, the disclosure provides that the film support and the clamping jaws are coupled with transmitters which assume positions with respect to a displacement direction of the film support in dependence on the clamping positions of the respective pairs of clamping jaws. Associated with the transmitters are receivers which, together with an actual value transmitter responsive to movement of the film support, are connected to a measured value processing arrangement. The disclosure radiographic installation is particularly suited for utilization with under-table spot film devices.
