Comparison of simulated parallel transmit body arrays at 3 T using excitation uniformity, global SAR, local SAR and power efficiency metrics
PURPOSE: We compare the performance of 8 parallel transmit (pTx) body arrays with up to 32 channels and a standard birdcage design. Excitation uniformity, local SAR, global SAR and power metrics are analyzed in the torso at 3 T for RF-shimming and 2-spoke excitations. METHODS: We used a fast co-simu...
