Abstract
A low profile radio frequency coil (32, 44, 441, 442, 443) for use in a magnetic resonance imaging system includes a low profile antenna (34, 102, 202, 302) that is configured to resonate at about a magnetic resonance frequency of the magnetic resonance imaging system. A generally planar inductor (110, 112, 210, 240, 310) is electrically connected or coupled with the low profile antenna. The generally planar inductor provides selected frequency filtering of a radio frequency signal received by or transmitted by the low profile antenna.
