摘要:
Various methods and systems are provided for selecting radio frequency coil array comprising a plurality of coil elements for magnetic resonance imaging. In one embodiment, the method includes grouping the plurality of coil elements into receive elements groups (REGs) according to REGs information; generating REG sensitivity maps; determining, for each REG, signal in a region of interest (ROI) and signal in an annefact source region based on the REG sensitivity maps; selecting one or more REGs based on the signal in the ROI and the signal in the annefact source region; and scanning the ROI with the coil elements in the one or more selected REGs being activated and the coil elements not in any selected REGs being deactivated. In this way, annefact artifacts in the reconstructed image may be reduced.
