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： 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： A gating and target device for an x-ray examination apparatus has a secondary radiation diaphragm and an x-ray film cassette, the secondary radiation diaphragm having two diaphragm plates disposed in parallel planes, and moveable relative to each other so that the diaphragm plates can be adjusted to at least partially overlap. Each of the diaphragm plates has a diaphragm opening therein, with the remainder of the plate being impermeable to x-radiation, so that by adjusting the relative positions of the plates, an opening of selected size may be formed by either one of said diaphragm plates at least partially covering the opening of the other diaphragm plate. To minimize the thickness of the device, and thus to minimize the distance between the target x-ray film and an examination subject, one of the diaphragm plates has a scattered ray grid structurally integrated within the opening of that plate.

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 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： 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.

摘要： The disclosure relates to an x-ray examination apparatus comprising an examination table, a patient support platform resting on the examination table, an x-ray source, a remotely directed collimator for restricting the radiation beam according to cassette size (film format), a longitudinal transport carriage movable along the length of the patient support platform, and a cassette drawer capable of insertion in the longitudinal transport carriage, with clamping jaws for the purpose of the support-mounting of an insertable x-ray film cassette. In order to render possible a free removal of the cassette drawer during fluoroscopy, in spite of the necessary transmission of the scanned cassette dimensions for the purpose of collimator adjustment during radiography, the longitudinal transport carriage carries two sensors, coupled with one mechanical-electrical transducer each, for sensing the length and width of the x-ray film cassette clamped in the inserted cassette drawer. The sensors are resiliently urged to a rest position clear of the image intensifier, while being actuated by cassette insertion to assume their respective sensing positions.

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.
