Abstract: An X-ray examination device has an X-ray tube, a primary X-ray diaphragm attached to the X-ray tube and disposed close to the focus thereof, a patient support bed, and an X-ray exposure device disposed behind the patient's support bed in the radiation direction having an X-ray image carrier and a stray radiation screen. The primary X-ray diaphragm includes a first slit beam collimator for generating a fan-shaped radiation beam and the X-ray exposure device has a second slit beam collimator in the form of two displaceable diaphragm plates and an adjustment device for moving the plates relative to one another to achieve a slit opening therebetween of desired width. The examination device further includes synchronized drive units for moving the X-ray tube and the second beam collimator in fixed alignment for sweeping the radiation beam across a patient on the support bed.

Abstract: In an exemplary embodiment, a patient support platform, resting on a frame, can be irradiated in a shadow-free fashion, and is provided with two longitudinally extending support rails for the mounting of accessories, and a collector basin for collecting outflowing contrast medium. To avoid grooves and cracks where fluids can accumulate and make cleaning very difficult, a single-piece, smooth support plate is provided for entirely covering the upper surface and the four lateral edges--adjoining the upper surface--of the patient support platform, and the support rails are moved to the longitudinal sides of the support plate. In addition, the support plate can be provided with a flat depression with marginal edges extending at a shallow angle for minimized attenuation of incident X-rays. The support rails can manifest a T-shaped cross section and can be mounted with the foot of the "T" on the drawn-down lateral edges of the examination table.

Abstract: An X-ray examining apparatus having X-ray exposure installation, an inclinable support bed for a patient, and an overhead X-ray tube which is connected with the X-ray exposure installation. The X-ray exposure installation together with the X-ray tube is rotatably supported about a horizontal axis, and the patient support bed for the patient longitudinally slidably carried on the X-ray exposure installation. In this manner, the X-ray tube together with its high voltage cable, and the X-ray exposure installation, are commonly supported at a location which is fixed with respect to the horizontal direction. The X-ray exposure installation may be fastened to a carrier or support tube which envelops the horizontal axis. The carrier tube may be supported, so as to rotate about the horizontal axis, on a carriage which is slidable in a vertical direction along a separating wall.
