Abstract

A positioning device for a mobile x-ray detector, an x-ray device containing such a mobile positioning device, and a method mutually align a mobile x-ray detector and an x-ray emitter in relation to one another. In order to enable exact mutual alignment or positioning of the mobile x-ray detector in relation to the x-ray emitter, a positioning device is used for a mobile x-ray detector. The positioning device contains at least one marker and/or at least one sensor for determining the position and/or the orientation of the positioning device and contains a number of connection elements for establishing a mechanical connection between the positioning device and the mobile x-ray detector.

First claim

The invention claimed is:

1. A positioning device for a mobile x-ray detector, comprising:
at least one device selected from the group consisting of at least one marker and at least one sensor for determining a position of the positioning device;
a number of connection elements for establishing a mechanical connection between the positioning device and the mobile x-ray detector; and
an arm which is movable from a first position to a second position and back again, said arm having a free end at which at least one of said marker or said sensor is disposed, wherein at least one of said marker or said sensor has a greater distance from the mobile x-ray detector in the second position of said arm than in the first position of the arm.

2. The positioning device according to claim 1 , wherein at least one of said marker defines or said sensor determines an orientation of the positioning device.

3. The positioning device according to claim 1 , further comprising:
a computer unit for determining at least one of a position or an orientation of the mobile x-ray detector; and
an interface for providing at least one of position data or orientation data.

4. The positioning device according to claim 1 , wherein said connection elements are embodied to establish at least one of a latching or snap-in connection between the positioning device and the mobile x-ray detector.

5. The positioning device according to claim 1 , wherein the positioning device is a frame for at least one of accommodating or holding the mobile x-ray detector.

6. An x-ray device, comprising:
an x-ray emitter;
a mobile x-ray detector; and
a positioning device being connectable to said mobile x-ray detector, said positioning device containing:
at least one device selected from the group consisting of at least one marker and at least one sensor for determining a position of said positioning device;
a number of connection elements for establishing a mechanical connection between said positioning device and said mobile x-ray detector; and
an arm which is movable from a first position to a second position and back again, said arm having a free end at which at least one of said marker or said sensor is disposed, wherein at least one of said marker or said sensor has a greater distance from the mobile x-ray detector in the second position of said arm than in the first position of the arm.

7. The x-ray device according to claim 6 , further comprising a positioning aid connectable to said x-ray emitter or to a ceiling mount, said positioning aid containing:
at least one further device selected from the group consisting of a further marker and a further sensor for establishing at least one of the position or an orientation of said positioning device for said mobile x-ray detector; and
a number of further connection elements for establishing a mechanical connection between said positioning aid and said x-ray emitter or the ceiling mount.

8. A method for mutually aligning a mobile x-ray detector and an x-ray emitter in relation to one another, which comprises the following steps of:
connecting the mobile x-ray detector to a positioning device with an aid of a number of connection elements of the positioning device;
determining a position of the mobile x-ray detector;
providing position data with an aid of the positioning device; and
aligning the mobile x-ray detector in relation to the x-ray emitter, and/or vice versa, using the position data.

9. The method according to claim 8 , which further comprises:
determining an orientation of the mobile x-ray detector and providing orientation data with an aid of the positioning device; and
carrying out an alignment of the mobile x-ray detector in relation to the x-ray emitter, and/or vice versa, using the orientation data.
