We present a simultaneous δ B0 and high-dynamic range B1 mapping technique using an adiabatic partial passage pulse. The double angle method, the gold standard for B1 mapping, requires 66% longer to acquire the same B1 range. The high dynamic range is useful for mapping the fields from ablation wires or surface coils, where significant B0 variation will also be present.
