Several differing coil arrays at 3T and 7T were simulated and evaluated for B1+ efficiency relative to net input power, global SAR and local SAR to demonstrate the importance of normalizing efficiency in terms of both input power and SAR. Large volume efficiency metrics are better for coils that have variation in the z-axis.
