Abstract: An x-ray diagnostics apparatus for obtaining an x-ray exposure of a bedridden patient permits the exposure to be obtained without moving the patient from the bed. The patient bed has two patient bearing surfaces. The patient lies on the upper surface, and a lower surface is vertically adjustable beneath the upper surface. When the lower surface is lowered to permit the introduction of an x-ray cassette between the upper and lower surfaces, the upper surface is supported, such as by a fabric tentered to the bed frame. An optical system is provided for accurately positioning the x-ray film cassette, and a wireless transmission path for an automatic exposure unit may also be provided.

Abstract: 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.

Abstract: 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.

Abstract: 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.
