Abstract: The disclosure relates to a sheet film changer comprising a photographic exposure station, at least one supply magazine for the film sheets, and two discrete, synchronously driven conveyor belts which are disposed one above the other in the vicinity of the exposure station for conveying film sheets clamped between them. The conveyor belts transport the film sheets from a receiving location associated with the supply magazine to the photographic exposure station and then to a release location. In order to facilitate fluoroscopy when no film sheets are disposed in the path of rays, the conveyor belts themselves can be readily irradiated and are provided with intensifier foils only at specified sections. In order to achieve a greater flexibility with regard to the photographic conditions, at least two intensifier foils with different intensification properties are secured to each of the two conveyor belts. The sheet film changer is used for X-ray diagnosis.

Abstract: An X-ray examining apparatus including a tomographic exposure installation, with an adjusting or positioning drive for the laminagraphic height displacement, as well as an installation for effecting the marking or indentifying of the currently set laminagraphic height on the tomographic X-ray exposures. In an X-ray examining apparatus of the above-mentioned type there is, accordingly, inventively associated with the X-ray film sheets which are being exposed, a scale or graduated dial which is provided with laminagraphic height gradations and coupled with the positioning drive for the laminagraphic height for the imaging of the area identifying the currently set laminagraphic height.
