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.
