Abstract

A holder for a local coil for an imaging system such as a magnetic resonance tomography (MRT) hand coil holder is provided. The MRT hand coil holder has recesses in side parts of the holder. A hand of a patient may be positioned between the side parts. The recesses in the side parts of the holder are each configured to accommodate at least one local coil.

First claim

The invention claimed is:

1. A holder for a local coil for an imaging system, the holder comprising:
a base;
side parts positioned on the base, between which a hand of a patient is positionable, wherein a first of the side parts is configured to slide relative to a second of the side parts, the second side part is configured to slide relative to the first side part, or the first side part and the second side part are configured to slide relative to each other, at least one of the first side part and the second side part being configured to slide in a direction parallel to the base, towards and away from the other of the first side part and the second side part; and
a recess in each of the side parts,
wherein each of the recesses is configured to accommodate at least one local coil.

2. The holder as claimed in claim 1 , wherein the holder is a magnetic resonance tomography (MRT) hand coil holder.

3. The holder as claimed in claim 2 , wherein the MRT hand coil holder is for MRT imaging of the hand.

4. The holder as claimed in claim 1 , further comprising a fastening device for fastening the holder to a magnetic resonance tomography (MRT) patient table.

5. The holder as claimed in claim 1 , wherein the recesses are located on opposing sides of the holder to allow the hand of the patient to be positioned in between.

6. The holder as claimed in claim 1 , wherein the coils are insertable into the recesses.

7. The holder as claimed in claim 1 , wherein the coils are insertable into one of the recesses.

8. The holder as claimed in claim 7 , wherein the coils are insertable into the one recess with latching strips on one of the coils, the latching strips engaging in an elastic manner in latching recesses in one of the side parts.

9. The holder as claimed in claim 1 , wherein the side parts include additional recesses for cables leading to the local coils.

10. The holder as claimed in claim 1 , wherein one or both of the side parts are movable counter to a direction of movement of the other side part.

11. The holder as claimed in claim 1 , wherein the side parts have padding.

12. The holder as claimed in claim 1 , wherein the side parts have a closing mechanism, a latching mechanism, or a combination thereof to fix the side parts in place during an imaging examination.

13. The holder as claimed in claim 3 , further comprising a fastening device for fastening the holder to a magnetic resonance tomography (MRT) patient table.

14. The holder as claimed in claim 3 , wherein the recesses are located on opposing sides of the holder to allow the hand of the patient to be positioned in between.

15. The holder as claimed in claim 3 , wherein the coils are inseratable into the recesses.

16. The holder as claimed in claim 3 , wherein the coils are insertable into one of the recesses.

17. The holder as claimed in claim 16 , wherein the coils are insertable into the one recess with latching strips on one of the coils, the latching strips engaging in an elastic manner in latching recesses in one of the side parts.

18. The holder as claimed in claim 3 , wherein the side parts include additional recesses for cables leading to the local coils.
