Abstract
Systems and methods of correcting eddy current-induced background phase (EC-BP) in magnetic resonance imaging (PC-MRI) data. The method includes acquiring a slice of interest (SOI) at a first table position using a magnetic resonance imaging (MRI) scanner, the slice of interest having a predetermined imaging orientation and being acquired having predetermined gradient waveforms; acquiring at least one additional slice at a second table position using the MRI scanner, the at least one additional slice having a same imaging orientation as the slice of interest and being acquired using the same gradient waveforms as the slice of interest; determining time-averaged phase maps from the slice of interest and the at least one additional slice; determining a correction map from the time-averaged phase maps; and correcting a background phase (BP) of the slice of interest using the correction map.
