Abstract

A shim coil arrangement is provided for a magnetic resonance tomography system. The shim coil arrangement includes a printed circuit board, a plurality of spacers, and at least one shim coil. The plurality of spacers are arranged on the printed circuit board. The at least one shim coil is arranged on the printed circuit board.

Claims (12)

1. A shim coil arrangement for a magnetic resonance tomography system, the shim coil arrangement comprising:

a printed circuit board comprising one side with a plurality of spacers integrated with the printed circuit board, and an opposite side coated with copper with at least one shim coil etched in the copper;

wherein the plurality of spacers are configured to contact a shim coil of an adjacent shim coil arrangement.

2. The shim coil arrangement of claim 1 , wherein the printed circuit board is made of an epoxy-glass laminate.

3. The shim coil arrangement of claim 1 , wherein the printed circuit board has a smooth surface on at least one side of the printed circuit board.

4. The shim coil arrangement of claim 1 , wherein the plurality of spacers is positioned on a side opposite to the one side coated with copper.

5. The shim coil arrangement of claim 1 , wherein the plurality of spacers are positioned on a non-conducting side of the printed circuit board opposite to the side coated with copper.

6. The shim coil arrangement of claim 1 , wherein at least two spacers of the plurality of spacers are configured longitudinally.

7. The shim coil arrangement of claim 1 , wherein at least two spacers of the plurality of spacers extend in parallel to one another running in a same direction.

8. The shim coil arrangement of claim 1 , wherein at least two spacers of the plurality of spacers extend in orthogonal directions to one another.

9. The shim coil arrangement of claim 1 , wherein the plurality of spacers are molded onto the printed circuit board, are integrated on the printed circuit board, or are molded onto the printed circuit board and integrated on the printed circuit board.

10. The shim coil arrangement of claim 1 , wherein the plurality of spacers are raised sections on a side of the printed circuit board.
