Abstract
An apparatus for movably suspending an x-ray grid. The apparatus has a carrier module, in or on which the x-ray grid is arranged, and a linkage. The linkage is configured to rotate the carrier module about an axis which is vertical to the x-ray grid and/or to translate the carrier module in the plane of the x-ray grid. An x-ray arrangement has an x-ray emitter, an x-ray detector and one or more apparatus for suspending the x-ray grid between the emitter and detector. The apparatus provides for play-free kinematics which is more cost-effective than the use of known precision drives.
Claims17
An apparatus for movably suspending an x-ray grid, the apparatus comprising:
- a carrier module carrying the x-ray grid thereon or therein;
- and
- a linkage having a shape selected from the group consisting of trapezoid and parallelogram;
- and
- said linkage being configured to effect at least one of the following:
- rotate said carrier module about an axis extending vertically to the x-ray grid;
- or
- move said carrier module in translation in a plane of the x-ray grid.
An apparatus for movably suspending an x-ray grid, the apparatus comprising:
- a carrier module carrying the x-ray grid thereon or therein;
- a linkage;
- a motor-driven linear drive with a spindle disposed along a diagonal of said linkage, said spindle being configured to move said carrier module by changing a length of the diagonal;
- and
- said linkage configured to effect at least one of the following:
- rotate said carrier module about an axis extending vertically to the x-ray grid;
- or
- move said carrier module in translation in a plane of the x-ray grid.
