Abstract

An X-ray device includes a C-bracket having a radiation detector rotatably mounted on the C-bracket. The radiation detector may be rotated by a motor drive. The axis of rotation is perpendicular to the detector surface. The motor drive is a torque motor that includes a stator and a rotor. The radiation detector is coupled to the rotor.

Claims

1. An x-ray device comprising:

a C-bracket; and

a radiation detector rotatably mounted on the C-bracket;

wherein the radiation detector is configured to be rotated by a torque motor, the torque motor comprising a stator and a rotor, wherein the radiation detector is coupled to the rotor, and wherein an axis of rotation of the radiation detector is perpendicular to a surface of the radiation detector.

2. The x-ray device of claim 1, wherein the radiation detector is connected directly to the rotor, or wherein an adapter is arranged between the rotor and the radiation detector.

3. The x-ray device of claim 1, wherein the rotor is detachably connected to the radiation detector, or wherein the rotor and the radiation detector are detachably connected by a screw connection to an adapter, the adapter being arranged between the rotor and the radiation detector.

4. The x-ray device of claim 3, wherein the radiation detector comprises a mounting plate, the mounting plate comprising a plurality of apertures, each aperture of the plurality of apertures being configured for receiving a screw;

and wherein the rotor or the adapter comprises a plurality of threaded holes, each threaded hole of the plurality of threaded holes being configured to receive the screw.

5. The x-ray device of claim 4, wherein the mounting plate is arranged on an outside or an interior of a housing of the radiation detector, the housing comprising an opening that faces towards the rotor or the adapter.

6. The x-ray device of claim 3, further comprising a detector unit, wherein the radiation detector comprises a mounting plate, and wherein the detector unit is arranged by holding elements on the mounting plate on a side of the mounting plate facing away from the rotor or the adapter.

7. The x-ray device of claim 6, wherein dimensioning of the mounting plate corresponds substantially to dimensioning of the detector unit.

8. The x-ray device of claim 1, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.

9. The x-ray device of claim 8, wherein a housing of the radiation detector comprises a hollow-cylindrical projection configured to fit around an outside of the hollow-cylindrical housing-type projection of the C-bracket.

10. The x-ray device of claim 2, wherein the rotor is detachably connected to the radiation detector, or wherein the rotor and the radiation detector are detachably connected to the adapter by a screw connection.

11. The x-ray device of claim 10, wherein the radiation detector comprises a mounting plate, the mounting plate comprising a plurality of apertures, each aperture of the plurality of apertures being configured for receiving a screw;

and wherein the rotor or the adapter comprises a plurality of threaded holes, each threaded hole of the plurality of threaded holes being configured to receive the screw.

12. The x-ray device of claim 4, further comprising a detector unit, wherein the detector unit is arranged by holding elements on the mounting plate on a side of the mounting plate facing away from the rotor or the adapter.

13. The x-ray device of claim 5, further comprising a detector unit, wherein the detector unit is arranged by holding elements on the mounting plate on a side of the mounting plate facing away from the rotor or the adapter.

14. The x-ray device of claim 2, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.

15. The x-ray device of claim 3, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.

16. The x-ray device of claim 4, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.

17. The x-ray device of claim 5, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.

18. The x-ray device of claim 6, wherein the C-bracket comprises a hollow-cylindrical, housing-type projection configured for receiving a cylindrical torque motor.
