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.
