Abstract

An adaptive magnetic resonance (MR) local coil includes at least one conductor structure. The at least one conductor structure is electrically conductive. The at least one conductor structure is at least partially ductile and/or pliable.

First claim

The invention claimed is:

1. A local coil comprising:
at least one conductor structure comprising one or more rigid sections and one or more flexible sections,
wherein the at least one conductor structure is electrically conductive,
wherein the at least one conductor structure is at least partially ductile, pliable, or ductile and pliable, and
wherein the one or more flexible sections of the at least one electrically conductive conductor structure comprise at least one coil spring.

2. The local coil of claim 1 , wherein the at least one conductor structure comprises carbon nanotubes.

3. The local coil of claim 1 , wherein the at least one conductor structure comprises single strands, solid wires, or single strands and solid wires.

4. The local coil of claim 1 , wherein the at least one conductor structure has at least one textile fabric.

5. The local coil of claim 4 , wherein the at least one textile fabric is woven, crocheted, knitted, braided, twisted, or any combination thereof.

6. The local coil of claim 4 , wherein the at least one textile fabric is spatially designed.

7. The local coil of claim 4 , wherein the at least one textile fabric is flat in design.

8. The local coil of claim 1 , wherein the at least one conductor structure comprises a plurality of conductor structures with a same preferred direction.

9. The local coil of claim 1 , wherein the at least one conductor structure comprises a plurality of conductor structures that are crossed over.

10. The local coil of claim 1 , further comprising at least one supporting structure.

11. The local coil of claim 10 , wherein the at least one supporting structure is at least partially ductile, pliable, or ductile and pliable.

12. The local coil of claim 10 , wherein the at least one conductor structure is arranged on the at least one supporting structure.

13. The local coil of claim 10 , further comprising a plurality of supporting structures that are arranged in parallel to each other.

14. The local coil of claim 1 , wherein the at least one conductor structure follows a zigzag-shaped course, a meandering course, or a combination thereof.

15. The local coil of claim 1 , wherein the at least one conductor structure is arrangeable on a cylinder.

16. The local coil of claim 1 , wherein the at least one spring comprises at least one conical spring, telescopic spring, flat spring, or any combination thereof.

17. The local coil of claim 1 , further comprising at least one protective sleeve that is arranged around the at least one conductor structure.

18. The local coil of claim 1 , further comprising at least one matching circuit.

19. The local coil of claim 1 , wherein the at least one conductor structure comprises an elastic conductor structure.

20. A magnetic resonance device comprising:
a local coil comprising:
at least one conductor structure comprising one or more rigid sections and one or more flexible sections,
wherein the at least one conductor structure is electrically conductive, wherein the at least one conductor structure is at least partially ductile, pliable, or ductile and pliable, and
wherein the one or more flexible sections of the at least one electrically conductive conductor structure comprise at least one coil spring.
