Abstract
A diaphragm apparatus for the collimation of an X-ray bundle of an X-ray device is provided for scanning an examination object. An X-ray device including the diaphragm apparatus is also provided. In an embodiment, the diaphragm apparatus includes two diaphragms in the form of slotted diaphragms arranged in series in the direction of the X-rays and mounted to be positionable with respect to one another. Each of the diaphragms includes a fixed diaphragm aperture corresponding to maximum collimation of the X-ray bundle and a region that is impermeable to X-rays, which in each case includes an extension corresponding to the diaphragm aperture corresponding to the maximum collimation.

A diaphragm apparatus for a collimation of an X-ray bundle of an X-ray device provided for scanning an examination object, the diaphragm apparatus comprising:
- two diaphragms, each in the form of slotted diaphragms, arranged in series in a feed direction of the X-rays and each of the two diaphragms being positionable with respect to one another, wherein each of the two diaphragms includes
- a fixed diaphragm aperture corresponding to maximum collimation of the X-ray bundle, and
- a region impermeable to X-rays, including an extension corresponding to diaphragm aperture corresponding to the maximum collimation, wherein the two diaphragms are mounted movably in a direction transverse to a feed direction of the X-ray device.
