摘要： A supine torso radio frequency (RF) coil assembly for a magnetic resonance (MR) system is provided. The RF coil assembly includes an RF coil array and a lining. The RF coil array includes a plurality of RF coils each RF coil including a coil loop that includes a wire conductor, the wire conductor formed into the coil loop and a coupling electronics portion coupled to the coil loop. The plurality of RF coils form into a contoured portion, the contoured portion sized to receive at least part of a breast of a subject therein. The lining includes a contoured portion. The RF coil array is coupled to and distributed on the lining, the contoured portion of the RF coil array covering and conforming with the contoured portion of the lining.

摘要： Various systems are provided for magnetic resonance imaging (MRI). In one example, a method includes selecting a contour topology for operating a configurable radio frequency (RF) coil assembly, wherein the configurable RF coil assembly includes an array of conductive segments coupled via a plurality of switches, and the contour topology defines a configuration of one or more RF coil elements formed on the configurable RF coil assembly. The method further includes, during a receive mode, at least partially activating one or more subsets of switches of the plurality of switches according to the selected contour topology to form the one or more RF coil elements.
