A magnetic resonance (MR) system (10) minimizes noise for modes of an array of coils (281, 282,..., 28n). The system (10) includes an array of coils (281, 282,..., 28n) which share impedance. A plurality of preamplifiers (301, 302,..., 30n) receive a plurality of signals from the array of coils (281, 282,..., 28n), and a plurality of matching circuits (321, 322,..., 32n) impedance match the array of coils (281, 282,..., 28n) to the plurality of preamplifiers (301, 302,..., 30n). A plurality of receivers (361, 362,..., 36n) oversample the plurality of preamplified signals at a plurality of different match values. Thereafter, a plurality of separate images may be reconstructed from the oversampled data, each image corresponding to a particular match value. Finally, the image with the highest SNR may be selected. |
