Figure 8

Power/SAR/excitation accuracy trade-offs obtained by varying the average power limit and by turning on the local SAR constraint (2-spokes pulses in the torso at 3 T). All pulses are designed using a least-square design strategy using the phase of a single MLS pulse as the target phase (the same target phase is used for all the pulses in this figure). In this case, moving from conservative local SAR constraints (orange L-curves) to more liberal local SAR constraints (red L-curves) has little effect on pulse power and excitation accuracy.
