We developed a nonlinear encoding method with
multiple RF coils based on the Bloch-Siegert shift. Simulated reconstructions
showed that higher B1 fields and lower off-resonance frequency shift improves
reconstruction quality. This approach is potentially promising as a replacement
for conventional gradient encoding providing excellent spatial encoding with
essentially silent imaging.
