Zusammenfassung:The present invention provides method and system for coil selection in magnetic resonance imaging to reduce phase wrap artifact. Various methods and systems are provided for a radio frequency coil array comprising a plurality of coil elements for magnetic resonance imaging. In one embodiment, a method includes grouping the plurality of coil elements into receive elements groups (REGs) according toREGs information, generating coil element sensitivity maps for the plurality of coil elements, generating REG sensitivity maps based on the REGs information and the coil element sensitivity maps, determining, for each REG, signals within a region of interest (ROI) and signals outside of the ROI based on the REG sensitivity maps, selecting one or more REGs based on the signals within the ROI and the signals outside of the ROI of each REG, and scanning the ROI with the coil elements in the selected REGs being activated and the coil elements not in any selected REGs being deactivated. In this way, phase wrap artifacts m
