Abstract: 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.

Abstract: A current cable trap includes a first body half having a first end and a second end and a second body half having a third end and a fourth end. The first body half and the second body half are configured to be snapped together about a cable to form a toroid body. The current cable trap includes a first wire and a second wire wrapped around the first body half and the second body half, respectively. The current cable trap includes a first printed circuit board and a second printed board disposed within a first receptacle and a second receptacle, respectively, when the first body half and the second body half are snapped together. The first printed circuit board and the second printed circuit board each provide electrical connection points with wire ends of both the first wire and the second wire.
