摘要： An X-ray examination apparatus has a base and a support connected by an arm arrangement. The support is connected to a holding device in which a curved carrier is displaceably mounted, the curved carrier having an X-ray emitter at one end and a radiation detector at an opposite end. An examination table is movable between the X-ray emitter and the radiation detector. The arm arrangement is composed of at least first and second arms. The first arm is rotatably mounted at a shaft at the base, and the second arm is rotatably mounted at a shaft at the carrier. The respective free ends of the first and second arms are rotatably connected to each other by another shaft. The carrier, without bothersome components of the stand beneath the examination table, can be rotated 90° from a head-adjusted position in both directions to lateral positions, while maintaining the isocenter at a fixed position, and the carrier also can be lowered to the floor on which the base is disposed. For this purpose, the first and second arms are disposed in different planes and have respective lengths, dependent on the position of the shaft at the base and the distance between the shaft of the support and the central beam of the X-ray emitter, so that the curved carrier, by means of the arms, can be rotated around an intersecting point formed by the central beam of the X-ray emitter cutting the center line of the examination table, with a centrally head-adjusted stand.

摘要： An x-ray examination apparatus has a base with at least one fixed part and one carriage that can be vertically shifted in relation to the fixed part. The carriage is provided with a horizontally projecting shaft, to which an apparatus component is mounted and which has a center axis around which the apparatus component can rotate. A pulley with a peripheral surface that is at least partially round is rotationally mounted to the shaft and is firmly connected to the apparatus component. A first pair of wheels is arranged at the fixed part of the base and a connector is provided to connect the pulley to the wheels so that whenever the wheels are respectively simultaneously rotated in different directions, the pulley and thus the apparatus component are vertically shifted and whenever the wheels are rotated in the same direction, the pulley and thus the apparatus component are caused to rotate around the center axis.
