Abstract

A shoulder coil for a magnetic resonance imaging device includes a bottom part and one or more top part elements that may be moved relative to the bottom part. The one or more top elements each have at least one coil therein.

First claim

The invention claimed is:

1. A shoulder coil for a magnetic resonance imaging device, the shoulder coil comprising:
a bottom part; and
at least two top part elements that are directly connected to the bottom part and are moveable relative to the bottom part, at least one coil being located in each top part element of the at least two top part elements,
wherein two top part elements of the at least two top part elements are hingedly openable and closeable relative to the bottom part in different directions that are approximately perpendicular to one another, the two top part elements being closeable, such that the two top part elements are positioned with one of the two top part elements on top of the other of the two top part elements.

2. The shoulder coil as claimed in claim 1 , wherein the bottom part is configured such that during magnetic resonance tomography (MRT) imaging, the bottom part is located under a patient, on an examination table, or under the patient and on the examination table.

3. The shoulder coil as claimed in claim 1 , wherein a top part element of the at least two top part elements is hingeable in a direction from next to a shoulder to be examined into a position partially or completely above the shoulder.

4. The shoulder coil as claimed in claim 3 , wherein another top part element of the at least two top part elements is hingeable in a direction from next to the shoulder to be examined into a position partially or completely above the shoulder.

5. The shoulder coil as claimed in claim 1 , wherein a top part element of the at least two top part elements is hingeable in a direction from laterally, cranially, or laterally and cranially next to a shoulder to be examined into a position partially or completely above the shoulder.

6. The shoulder coil as claimed in claim 1 , wherein at least one top part element of the at least two top part elements includes a plurality of coils.

7. The shoulder coil as claimed in claim 1 , wherein at least one top part element of the at least two top part elements includes a plurality of coils,
wherein first coils of the plurality of coils are connectable to an electronic output device of the shoulder coil, a magnetic resonance tomography (MRT) device, or the electronic output device and the MRT device, and
wherein second coils of the plurality of coils are not connected to the electronic output device, the MRT device, or the electronic output device and the MRT device when the first coils are connected to the electronic output device, the MRT device, or the electronic output device and the MRT device.

8. The shoulder coil as claimed in claim 1 , wherein at least one top part element of the at least two top part elements is a hinged element that is hingeable relative to the bottom part.

9. The shoulder coil as claimed in claim 1 , wherein the bottom part has a mirror-symmetrical design.

10. The shoulder coil as claimed in claim 9 , wherein the mirror-symmetrical design is configured to allow use of the bottom part for a right shoulder and a left shoulder.

11. The shoulder coil as claimed in claim 10 , wherein the mirror-symmetrical design is configured to allow use of the bottom part for the right shoulder at a zero degree position and for the left shoulder at a ninety degree position.

12. The shoulder coil as claimed in claim 1 , wherein the two movable top part elements are placeable on each other, and
wherein the two moveable top part elements are arranged on the bottom part so as to be movable with respect to the bottom part.

13. The shoulder coil as claimed in claim 1 , further comprising a cable outlet, wherein the cable outlet is located in a center of the shoulder coil, on an axis of symmetry of the shoulder coil, or in the center of and on the axis of symmetry of the shoulder coil.

14. The shoulder coil as claimed in claim 1 , wherein top part elements of the at least two top part elements are arranged on the bottom part so as to be hinged relative to the bottom part by at least 90 degrees.

15. The shoulder coil as claimed in claim 14 , wherein the top part elements are arranged on the bottom part so as to be hinged relative to the bottom part by more than 150 degrees.

16. The shoulder coil as claimed in claim 14 , wherein the top part elements are arranged on the bottom part so as to be hinged relative to the bottom part by at least 180 degrees.
