摘要： A radio frequency receive coil (50) includes an antenna (52, 52′) that is tuned to a magnetic resonance frequency to detect a magnetic resonance signal. Electronics (54) disposed on or with the antenna (52, 52′) as a unitary structure include compression circuitry (102, 114, 202, 214, 230, 330, 430, 530) that compresses the magnetic resonance signal at a gain controlled by a gain control signal to produce a compressed magnetic resonance signal. The electronics (54) generate a reduced dynamic range representation of the magnetic resonance signal based on the compressed magnetic resonance signal. The reduced dynamic range representation of the magnetic resonance signal is communicated off the receive coil.

摘要： 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.

摘要： A radio frequency receive coil for receiving a magnetic resonance signal includes a radio frequency antenna. The radio frequency antenna includes one or more electrical conductors (72, 74, 76, 78, 172, 173, 176, 180, 252, 254), at least one of which is a substantially hollow conductor (72, 78, 172, 252, 254). At least one electrical component (100, 110, 110′, 110″, 140, 160, 200) is mounted to be shielded from interfering with the MR signal by disposing it inside the substantially hollow conductor. The at least one electrical component can be, for example, a battery (100, 160, 200), a storage capacitor (140), or coil electronics (110, 110′,110″).
