Systems and methods for the selection of and application of RF power to a plurality of transmit and/or transmit/receive coil elements to decrease patient SAR and to limit the potential for artifact problems. Without any change to the hardware or software of an MR scanner, the present local coil system provides system logic and coil design flexibility such that only transmit coil elements that are required for a particular portion of an MR scan will be utilized at that time. The local coil system may include any combination of transmit-only, receive-only and transmit/receive coil elements as part of the coil system (array of coil elements). The logic controller of the local coil system gathers input data from the MR scanner, from the attached coil elements and optionally from one or more sensors attached to the coil system itself.
