Magnetic field modeling with the multi-coil approach has been used to generate anatomy-matched magnetic field shapes that are spatially specific enough for the selective excitation of individual regions in 2-dimensional slices with single frequency-selective RF pulses. The low SAR method is demonstrated for brain extraction and outer-volume-suppression (i.e. excitation of everything but the brain) in the mouse at 9.4 Tesla.
