Abstract

A local coil positioning arrangement is proposed for positioning at least one local coil at an adjustable distance from a Mayfield head fixing arrangement. The local coil positioning arrangement has a local coil holder for accommodating a local coil and a fixing arrangement for fixing the local coil holder at an adjustable distance to the head fixing arrangement.

Claims

1-15. -15. (canceled)

16. A local coil positioning arrangement, comprising:

a local coil for imaging a head of a patient;

a local coil holder for accommodating the local coil;

a head fixing arrangement for keeping the head of the patient still; and

a fixing arrangement for fixing the local coil holder at an adjustable distance from the head fixing arrangement.

17. The local coil positioning arrangement as claimed in claim 16, wherein the local coil holder comprises at least two holder parts between which the local coil is fixed.

18. The local coil positioning arrangement as claimed in claim 17, wherein the at least two holder parts are two shells.

19. The local coil positioning arrangement as claimed in claim 17, wherein the at least two holder parts are connected to each other by connecting elements.

20. The local coil positioning arrangement as claimed in claim 19, wherein the connecting elements are rods.

21. The local coil positioning arrangement as claimed in claim 19, further comprising distancing elements extending entirely or partly in parallel to a direction of the adjustable distance.

22. The local coil positioning arrangement as claimed in claim 21, wherein the distancing elements are able to be fixed to the connecting elements in a number of positions.

23. The local coil positioning arrangement as claimed in claim 22, wherein the distancing elements are able to be fixed to the connecting elements by releasable attachment devices.

24. The local coil positioning arrangement as claimed in claim 21, wherein the distancing elements are attached to the head fixing arrangement by releasable attachment devices.

25. The local coil positioning arrangement as claimed in claim 16, wherein the head fixing arrangement comprises at least two shell parts that are able to be moved relative to each other and are able to be fixed to each other by a fixing device.

26. The local coil positioning arrangement as claimed in claim 16, wherein the head fixing arrangement comprises adjustment devices.

27. The local coil positioning arrangement as claimed in claim 16, wherein the head fixing arrangement is a Mayfield head fixing arrangement.

28. The local coil positioning arrangement as claimed in claim 16, wherein the local coil is packed into an envelope.

29. The local coil positioning arrangement as claimed in claim 16, further comprising a further local coil that is fixed to the head fixing arrangement.

30. The local coil positioning arrangement as claimed in claim 29, wherein the further local coil is packed into an envelope.

31. The local coil positioning arrangement as claimed in claim 16, wherein the local coil positioning arrangement consists of an MR-compatible material.
