We describe a new approach for performing channel compression for pTx in cases where the number of elements in the transmit coil exceeds the number of exciters. Unlike previous methods for channel compression, the current approach takes local SAR information into account and seeks to minimize SAR while obtaining a uniform flip angle distribution. We demonstrate mitigation of local SAR hotspots with the current approach and show 30% reduction in peak local SAR compared to a SAR unaware approach.
