B0 map is needed by many MR applications, for instance
EPI distortion correction. Field mapping is normally
accomplished via evaluating the phase evolution of
multi-echo gradient echo measurements, which is acquired
separately from routine scans and consume additional
time. In this abstract, a novel B0 mapping method is
presented, which reconstructs the field map via
exploiting the information provided by active shimming.
Its application on EPI distortion correction is
