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.
