A positioning device for an X-ray detector or an X-ray source is provided. The positioning device includes an arched arm, inside of which the X-ray detector or the X-ray source can be mounted in a manner that enables the detector or source to be displaced in the direction of the arch. The positioning device includes a base, inside of which the arched arm is mounted in a manner that enables the arched arm to be displaced in the direction of the arch. Either the X-ray detector is mounted in the positioning device and the X-ray source is placed separately therefrom or, conversely, the X-ray source is mounted in the positioning device and the X-ray detector is placed separately there from.

Positioning device for an X-ray detector

A motorized adjustable x-ray apparatus has a transmitter operable by AN operator for adjustment of a C-arm and mechanically connected with the C-arm. The transmitter allows adjustment of both an angulation angle and an orbital angle of the C-arm. The speed of the adjustment movement of the C-arm can be selected by actuation of the transmitter.

Motorized adjustable x-ray apparatus

The invention concerns a C-arm x-ray device with a non-isocentric C-arm on which an x-ray source is positioned and that can be orbitally or angularly rotated, whereby the C-arm x-ray device comprises a device fashioned to horizontally adjust the C-arm (which enables an adjustment of the C-arm within the plane of the C-arm) and a device fashioned to vertically adjust the C-arm, where the horizontal adjustment device and the vertical adjustment device are fashioned such that they can automatically move the central x-ray beam of the x-ray source back into the isocenter, given an orbital or angulatory rotation of the C-arm via the horizontal and vertical adjustment device. An appertaining method is also provided.
