Patent ID: 7221163

Claim:
A magnetic resonance system comprising: a magnetic resonance scanner having an examination volume adapted to receive an examination subject therein; a transmission antenna that emits radio frequency energy, at an excitation frequency, into the examination volume; a radio frequency source disposed relative to said examination volume, said radio frequency source emitting an electrical field oscillating at said excitation frequency; a barrier disposed between said radio frequency source and said examination volume to shield said examination volume from said electrical field generated by said radio frequency source; and said barrier being comprised of a plurality of individual resonators that each inherently resonate at said excitation frequency, each individual resonator comprising two capacitor surfaces, a first of said two capacitor surfaces facing said radio frequency source and a second of said two capacitor surfaces facing said examination volume, said first and second capacitor surfaces being electrically connected to each other via a coil, with said first and second capacitor surfaces not being otherwise electrically connected to each other.
