A light distributor for directing the light of the output image of an x-ray image intensifier to a number of different types of cameras in an x-ray diagnostics installation has a housing to which the cameras are attached with their respective beam path axes disposed perpendicularly relative to each other and perpendicularly relative to the axis of the beam path from the x-ray image intensifier. A first mirror deflects the beam from the x-ray image intensifier to one of the cameras, and a second moveable mirror is introducible into the beam path between the first mirror and the first camera to deflect the beam from the x-ray image intensifier onto a second camera.

Light distributor for an x-ray diagnostics installation

The invention relates to an x-ray apparatus comprising an apparatus base, a tiltable part, a displaceable carriage for x-ray parts running on the tiltable part along guide rails and having a spring weight compensation device having compensating forces adjustable by motor drive depending on the apparatus position, whereby at least one slot-shaped opening is provided on the carriage, one end of a one-armed load lever hinged to the tiltable part being displaceable in the slot-shaped opening. Between its ends, the load lever is pivotably connected to a sleeve seated in gliding fashion on a rod, the sleeve being supported with a spring at the one end of the rod whose other end is hinged to a nut displaceable by means of a motor-actuatable spindle, whereby the threaded spindle is arranged essentially parallel to the guide rails.

X-ray apparatus with spring weight compensation

At its outside, the table frame or support is provided with two symmetrical, circular drive paths into each of which a drive wheel engages. Two respective guide rails are arranged at the table frame or support at both sides thereof, two respective, stationary guide pegs engaging into these guide rails in the horizontal position, said guide rails being fashioned and directed or, respectively, curved such that, given adjustment of the tilting table out of the horizontal position, respectively two guide pegs leave their guide rail and the lower end of the table frame or support is lifted to such a degree that it lies above the floor level. The curvature of at least one pair of guide rails at both sides of the table frame or support is selected such that the tilting speed is roughly uniform.

X-ray diagnostics installation including a tilting table

An improved x-ray diagnostic apparatus having a table mounted on a table support and being tiltable on a support base to positions on each side from a horizontal position with one of the side positions being through 90.degree. characterized by a drive arrangement including a curved drive track on the table support engaged by drive wheels mounted on the support base and a guide arrangement including two spaced guide rails on the table support receiving guide pins or members of the support base when the table is in the horizontal position. When the table moves from the horizontal position, the guide rail of the upper end of the table disengages from its respective guide pin so that the guide rail at the lower end coacting with its guide pin and the support provided by the drive arrangement coact to maintain the lower end above the floor level. Preferably, the drive arrangement also includes a support arrangement having a curved support track engaging a support roller so that only tangential forces are applied between the drive wheel and drive track.

X-ray diagnostic device having a tiltable table

In an illustrative embodiment, a patient card insertable into the device has the patient data thereon light projected onto the x-ray film with the aid of a light source and an optical image reproducing system; variable data in addition to the data of the patient card are brought into the data field so as to be light-projected onto the x-ray film in a common region and with a common orientation.

Device for identifying x-ray films

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.

Sheet film changer

A hold-down device particularly for use in securing patients to examination tables and the like. The device includes mounting member for attachment to opposite sides of the examination table, one of the mounting members having first and second actuatable take-up drums controlled by a rachet connected handle, a belt is past from the first take-up drum across the patient to the other holder and around a free wheeling roll in that holder and back across the patient to the second take-up drum. The rolls are geared such that the second take-up drum revolves three times faster than the first take-up drum.

Patient securing device

An X-ray examining apparatus for the examination of upstanding patients, including an X-ray tube which is suspended from a support, and an exposure installation vertically adjustably mounted on a rack incorporating conveying means for the conveyance of film sheets from a supply magazine into an exposure position and from the exposure position into an automatic developing arrangement.
