Regularized Estimation of Magnitude and Phase of Multi-Coil B(1) Field via Bloch-Siegert B(1) Mapping and Coil Combination Optimizations
Parallel excitation requires fast and accurate B(1) map estimation. Bloch-Siegert (BS) B(1) mapping is very fast and accurate over a large dynamic range. When applied to multi-coil systems, however, this phase-based method may produce low SNR estimates in low magnitude regions due to localized excit...
