Abstract
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.
Claims9
A C-arm x-ray device, comprising:
- an x-ray source;
- a non-isocentric C-arm on which the x-ray source is positioned and that can be orbitally rotated, the C-arm x-ray device comprising:
- a horizontal adjustment device configured to horizontally adjust the C-arm which enables an adjustment of the C-arm within a plane of the C-arm;
- and
- a vertical adjustment device configured to vertically adjust the C-arm;
- the horizontal adjustment device and the vertical adjustment device being configured such that they can automatically move the central x-ray beam of the x-ray source back into the isocenter, given an orbital rotation of the C-arm.
A method for operating a 3-D C-arm x-ray device, comprising:
- providing a non-isocentric C-arm on the x-ray device;
- positioning an x-ray source for producing an x-ray beam at an isocenter within the C-arm;
- and
- orbitally rotating the C-arm during an examination of the x-ray source and simultaneously adjusting at least one of a horizontal adjustment device and a vertical adjustment device of the C-arm so that the x-ray beam is moved to or stays at the isocenter.
