摘要： 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.

摘要： An exemplary embodiment comprises a spot film device, a transport mechanism for the transport of an image layer carrier from a ready position into an exposure position and back, and a speed control for the drive motor. A certain time interval which is essentially caused by the transport operations always lies between triggering an X-ray exposure and the actual exposure of the image layer. In order to facilitate release of the X-ray exposure at the proper point in time, the disclosure provides that the overall transport time of the image layer carrier from the ready position into the exposure position is kept constant independently of the mass to be transported. Additionally, the transport time can also be kept constant independently of the different length of the transport path given sequencing of a sub-division program. An inventive X-ray examination device is particularly suited for employment in X-ray diagnostics.

摘要： An apparatus for reading out the latent image stored in a luminescent storage screen includes a storage screen having a stimulible phosphor layer and a layer of magnetic material, a scanning system which conducts a line-by-line scanning of the screen with a scan beam so that the luminescent storage screen is induced to luminesce pixel-by-pixel, and a conveyor system for moving the storage screen through the scan beam which includes a magnetic drive drum at least in the region of the scan beam. The magnetic drum by interaction with the magnetic layer of the storage screen holds the screen in place during a line scan, and is then rotated to advance the screen for the next line scan.

摘要： An X-ray film holder is disclosed comprising a bottom (1) to receive both the X-ray film (6) and image intensifying screens (7, 8) placed against the film, and a lid (2) to close the holder. The bottom (1) and the lid (2) are provided on all sides with grooves (3) and projections (4) that fit into one another so that the lid (2) can slide with respect to the bottom (1) by means of the guide system thus formed, and is interlocked with the bottom (1) on all sides when in the closed position. A foam cushion (10), placed within a cover (9) made of airtight material, which extends roughly over the entire film surface, is connected to the lid (2) by means of the wall of the cover. The cover (9) and the lid (2) are provided with interconnecting openings (11, 12) for the evacuation of the interior of the cover. The holder can therefore be opened after it is evacuated.

摘要： A cassette for holding a luminescent storage screen, in which an x-ray image is latently stored, has a housing with a cover consisting of a flexible, ferromagnetic material, to which the storage screen is attached. At least regions of the housing also consist of a ferromagnetic material, with the cover and the housing regions being magnetized. The cover with the screen attached thereto is thus held in place in the cassette in a light-tight fashion.

摘要： In an exemplary embodiment, a flat radiation beam is detected having a common electrode disposed parallel to the beam plane at one side and a common support with a series of individual conductors providing electrodes opposite successive portions of the common electrode and lying in a plane also parallel to the beam plane. The beam may be fan-shaped and the individual electrodes may be aligned with respective ray paths separated by uniform angular increments in the beam plane. The individual conductors and the connection thereof to the exterior of the detector housing may be formed on an insulator which can be folded into a T-shape for leading the supply conductors for alternate individual conductors toward terminals at opposite sides of the chamber.
