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.

First claim

The invention claimed is:

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 detachably connected 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.

3. The x-ray device of claim 1 , 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 comprises a plurality of threaded holes, each threaded hole of the plurality of threaded holes being configured to receive the screw.

4. The x-ray device of claim 3 , 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.

5. The x-ray device of claim 1 , 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.

6. The x-ray device of claim 5 , wherein dimensioning of the mounting plate corresponds substantially to dimensioning of the detector unit.

7. 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.

8. The x-ray device of claim 7 , 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.

9. The x-ray device of claim 1 , wherein an adapter is arranged between the rotor and the radiation detector.

10. The x-ray device of claim 1 , 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.

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 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 11 , 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 adapter.

13. The x-ray device of claim 10 , 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 adapter.

14. The x-ray device of claim 13 , wherein dimensioning of the mounting plate corresponds substantially to dimensioning of the detector unit.

15. 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 connected directly to the rotor, and
wherein an axis of rotation of the radiation detector is perpendicular to a surface of the radiation detector.

16. An x-ray device comprising:
a C-bracket;
a radiation detector rotatably mounted on the C-bracket; and
an adapter,
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,
wherein the adapter is arranged between the rotor and the radiation detector, and
wherein an axis of rotation of the radiation detector is perpendicular to a surface of the radiation detector.

17. An x-ray device comprising:
a C-bracket;
a radiation detector rotatably mounted on the C-bracket; and
an adapter,
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 detachably connected to the rotor by a screw connection to the adapter, the adapter being arranged between the rotor and the radiation detector, and
wherein an axis of rotation of the radiation detector is perpendicular to a surface of the radiation detector.
