Patent ID: 7622928

Claim:
A radio frequency coil comprising: an operative radio frequency circuit tuned to a magnetic resonance frequency and spatially configured to at least one of generate magnetic resonance in or receive magnetic resonance from a spatial region of interest; and a trap radio frequency circuit tuned to block a selected frequency, being disposed with the operative radio frequency circuit, and including at least a generally linear transmission line having a first end at which the operative radio frequency circuit and the trap radio frequency circuit are coupled together and a second end at which the generally linear transmission line is terminated with a termination impedance, the generally linear transmission line including an inner conductor and a coaxially arranged sheath, the inner conductor and the sheath being connected with the operative radio frequency circuit at the first end, the inner conductor and the sheath being electrically terminated at the second end by the termination impedance; wherein the generally linear transmission line is arranged along or forms a part of at least a portion of a conductor of the operative radio frequency circuit.
