Patent ID: 8704516

Claim:
A local coil for a magnetic resonance system, the local coil comprising: a dielectric former; one or more receive coils supported by the former; and a plurality of passive B 0 and B 1 field shims, each shim being configured to homogenize B 0 and B 1 fields adjacent the receive coils supported by the former, wherein the B 0 field is a main magnetic field generated by a main field coil through an examination region, and the B 1 field is emitted by a radio frequency (RF) coil in response to RF field transmit pulses; wherein the passive B 0 and B 1 field shims include pieces of a material, each piece of material being both electrically conductive and diamagnetic, paramagnetic or ferromagnetic; and wherein the pieces include capacitively coupled tiles.
