Table 1. Comparison of SAR values predicted using the VHP-Female surface CAD model with the values predicted by a 5 mm voxel model derived from the identical image dataset [71].

Nearly identical high-pass birdcage coil dimensions, coil landmark, and excitation type were used. All results are normalized to 1 μT B1+ field at the coil center.
