Analysis of SAR_10g distribution and target coverage in the brain of the human voxel model Duke. (a) SAR_10g distribution for four TR sizes using RF focusing for one arbitrary location in the brain. (b–d) Target coverage (TCxx = percent of volume covered by xx% of SAR_10g,max > 40 W/kg in the TR) was obtained for 702 locations across a mid-sagittal slice of the brain for (b) TC₂₅, (c) TC₅₀, and (d) TC₇₅. The gray dash lines highlight the superior, middle, and inferior regions of the brain. Regions with SAR_10g < 40 W/kg are marked dark blue.
