摘要： Various methods and systems are provided for radio frequency coil units for magnetic resonance imaging. In one example, a radio frequency (RF) coil unit for magnetic resonance imaging (MM) includes an outer layer forming an exterior of the RF coil unit, a pressure reservoir enclosed by the outer layer, wherein the pressure reservoir forms a sealed chamber, and an array of RF coil elements enclosed by the outer layer, wherein the array of RF coil elements is disposed outside of the sealed chamber of the pressure reservoir.

摘要： Various methods and systems are provided for a flexible, lightweight, and low-cost radio frequency (RF) trap for use in a magnetic resonance imaging (MRI) system. In one example, a radio frequency (RF) trap assembly for use in a magnetic resonance imaging (MRI) system is provided, comprising a twinax wire assembly having a plurality of looped portions, each ones of the plurality of looped portions tangentially in contact with a shielded cable, and at least one support structure for substantially maintaining the shape of the plurality of looped portions, the support structure surrounding a portion of the shielded cable, wherein the twinax wire assembly is tuned to a frequency suitable for increasing the impedance of the shielded cable.

摘要： Various methods and systems are provided for a current trap. In one example, the current trap has a spiral core made of a nonconductive material, a coiled wire having a plurality of turns wound around the spiral core, and one or more tuning capacitors physically attached to the spiral core and electrically connected to the coiled wire to form a resonance circuitry with the coiled wire.

摘要： Various methods and systems are provided for a current trap. In one example, the current trap has a flat core made of a nonconductive material, a coiled wire having a plurality of turns winding around the flat spiral core, and one or more tuning capacitors physically attached to the flat core and electrically connected to the coiled wire to form a resonant circuit with the coiled wire.
