Apparatus for the flexible positioning of a radiation source and a radiation detector

1. An apparatus for medical examinations, the apparatus comprising:

a first arm rotatably attached to a stand, the first arm including a cylindrical body at a first end of the first arm, the cylindrical body having a center and a side wall, the first arm being rotatably attached to the stand so that the first arm, with the cylindrical body, is rotatable about an axis that extends through the center of the body and an area for examining a patient, such that the first arm is not rotatable relative to the body, the first arm being configured to carry one of a radiation source and a radiation detector; and

a second arm that is rotatable about the axis, the second arm being movably disposed on an outer surface of the side wall of the body and being translatable along the side wall, such that when the second arm translates along the side wall, the second arm rotates about the axis relative to the body, the second arm extending away from the outer surface of the side wall to an arm section configured to carry the other of the radiation source and the radiation detector, the area for examining the patient being disposed between the radiation source and the radiation detector.

2. The apparatus as claimed in claim 1 , wherein the cylindrical body is rotationally symmetrical with respect to the axis.

3. The apparatus as claimed in claim 2 , wherein the cylindrical body is configured to receive a component of the apparatus.

4. The apparatus as claimed in claim 2 , further comprising a slip ring that transmits data, energy, or data and energy from the first arm to the second arm.

5. The apparatus as claimed in claim 2 , wherein a section of the first arm, a section of the second arm, or the section of the first arm and the section of the second arm are telescoping.

6. The apparatus as claimed in claim 2 , wherein the stand fastens the apparatus to a ceiling or a floor.

7. The apparatus as claimed in claim 1 , wherein the cylindrical body is configured to receive a component of the apparatus.

8. The apparatus as claimed in claim 7 , further comprising:

a first drive for the first arm; and

a second drive for the second arm,

wherein the second drive is arranged in the cylindrical body.

9. The apparatus as claimed in claim 8 , further comprising a slip ring that transmits data, energy, or data and energy from the first arm to the second arm.

10. The apparatus as claimed in claim 8 , wherein a section of the first arm, a section of the second arm, or the section of the first arm and the section of the second arm are telescoping.

11. The apparatus as claimed in claim 7 , wherein the radiation source and the radiation detector are arranged on the first arm and on the second arm, respectively.

12. The apparatus as claimed in claim 1 , wherein the radiation source and the radiation detector are arranged on the first arm and on the second arm, respectively.

13. The apparatus as claimed in claim 12 , wherein a section of the first arm, a section of the second arm, or the section of the first arm and the section of the second arm are telescoping.

14. The apparatus as claimed in claim 1 , wherein data, energy, or data and energy are transmitted from the stand to the first arm.

15. The apparatus as claimed in claim 14 , further comprising a slip ring that transmits data, energy, or data and energy from the first arm to the second arm.

16. The apparatus as claimed in claim 1 , wherein a section of the first arm, a section of the second arm, or the section of the first arm and the section of the second arm are telescoping.

17. The apparatus as claimed in claim 1 , wherein the stand fastens the apparatus to a ceiling or a floor.

18. The apparatus as claimed in claim 1 , further comprising a slip ring that transmits data, energy, or data and energy from the first arm to the second arm.
