Abstract

With a screen-filter-mirror unit installed in a sandwich architecture, an x-ray window on a patient or an object can also be visualized during an x-ray recording with a light window. It is advantageous that a screen, a filter and a light window unit are combined in just one unit and with a changing x-ray window only the unit is replaced and/or the attack angle of the unit and the alignment of a light source directed hereto can be attuned to one another.

First claim

The invention claimed is:

1. An apparatus, comprising:
a filter unit for homogenizing x-ray beams output by an x-ray source;
an alignable screen-filter-mirror unit for localizing an x-ray window and having a base plate with at least one cutout formed therein, said filter unit disposed in said at least one cutout; and
said filter unit having a filter layer with a light-reflecting layer and/or light-reflecting surface, said light-reflecting layer and/or light-reflecting surface of said filter unit is formed on a side of said base plate facing a light source.

2. The apparatus according to claim 1 , wherein said filter unit is embodied in a form of a film or a plate.

3. The apparatus according to claim 1 , wherein said filter unit is disposed in and/or on and/or under said at least one cutout of said base plate.

4. The apparatus according to claim 1 , wherein said alignable screen-filter-mirror unit is designed in a sandwich architecture.

5. The apparatus according to claim 1 , wherein light beams of the light source can be deflected according to a propagation of an x-ray beam of the x-ray source using said at least one light-reflecting layer and/or light-reflecting surface of said filter unit.

6. The apparatus according to claim 1 , wherein the light source can be positioned and aligned.

7. The apparatus according to claim 1 , further comprising a collimator, said alignable screen-filter-mirror unit can be positioned and aligned in said collimator such that the light source directed at said light-reflecting layer and/or light-reflecting surface of said alignable screen-filter-mirror unit deflects light beams originating herefrom on said light-reflecting layer and/or light-reflecting surface in a direction of an object and on the object positioned on an object couch maps a light window corresponding to the x-ray window on the object.

8. The apparatus according to claim 7 , further comprising at least one fin disposed in said collimator and can be aligned and/or activated such that the x-ray window formed by said cutout in said base plate can be partially minimized or faded-out on a patient or the object.
