Abstract

A device and to an associated method for a diagnostic apparatus. A housing unit can be aligned by way of a securing unit which is connected to the housing and it can be controlled in such a way that the diaphragm unit which is connected to the x-ray source and is arranged in the housing unit can be aligned in accordance with a specified position.

First claim

The invention claimed is:

1. A device, comprising:
a positionable fastening unit;
a housing unit disposed on said positionable fastening unit and including an X-ray source and a collimator unit arranged downstream of said X-ray source;
said collimator unit including displaceable collimator plates for delimiting a collimation field of said collimator unit;
a control unit for orienting said collimator unit together with said X-ray source, said control unit being configured to control said positionable fastening unit for rotating said collimator unit about a central beam of said X-ray source for aligning the collimation field with an examination region of interest.

2. The device according to claim 1 , wherein, for orienting said collimator unit, said control unit controls said positionable fastening unit such that while maintaining an orientation of the central beam of said X-ray source, according to a position and orientation of the examination region of interest, a collimation field orientable thereto is rotated by way of said positionable fastening unit to thereby achieve a match between the examination region of interest and the collimation field.

3. The device according to claim 1 , wherein said positionable fastening unit is formed of at least a first and a second movement unit mounted to a ceiling of a room and capable of travel in a plane.

4. The device according to claim 3 , wherein said positionable fastening unit is a multi-jointed arm.

5. The device according to claim 3 , which comprises a post of variable length mounted to said first or second movement units and having a free end, and a first connecting unit disposed on said free end, said first connecting unit being configured at least with one degree of freedom and having a connection to said housing unit with said X-ray source and said collimator unit arranged therein.

6. The device according to claim 1 , wherein said X-ray source and said collimator unit are fixed relative to one another.

7. An x-ray adjustment method, comprising:
providing a positionable fastening unit and a housing unit with an X-ray source and a collimator unit arranged downstream of the X-ray source arranged on the positionable fastening unit;
displacing collimator plates of the collimator unit for delimiting a collimation field of the collimator unit;
for orienting the collimator unit, controlling the positionable fastening unit to rotate the collimator unit together with the X-ray source while maintaining an orientation of a central beam of the X-ray source, to thereby align the collimation field with an examination region of interest until a match between the examination region of interest and the collimation field is achieved.

8. The method according to claim 7 , wherein the positionable fastening unit is movable in a plane.
