The typically large dynamic range of B1 fields generated by local transmit array coils are a limiting factor for fast and robust B1 mapping. This works extends the sensitivity range of quantitative B1 mapping techniques towards low B1 amplitudes incorporating the information gained from relative B1 maps into the B1 map reconstruction.
