A system and method for radio-frequency (RF) field mapping are provided. One method includes encoding a Bphase in at least one magnetic resonance (MR) excitation pulse as an encoded Bphase MR excitation pulse for at least a subset of a plurality of transmit channels within a magnetic resonance imaging (MRI) system. The method also includes encoding a Bmagnitude in at least one off-resonance MR pulse as an encoded Bmagnitude off-resonance MR pulse for at least a subset of the plurality of transmit channels within the MRI system. The method further includes determining one or more composite Bfields resulting from a transmission of the at least one encoded Bphase MR excitation pulse and the at least one encoded Bmagnitude off-resonance MR pulse.

A system and method of phase contrast imaging includes a system control programmed to acquire a first set of data and a second set of data via the RF coil assembly during a scan and acquire a third set of data and a fourth set of data via the plurality of magnetic field monitoring devices during the scan. A first single data set from the first and third sets of data is formed, and a second single data set from the second and fourth sets of data is formed. The system control is also programmed to reconstruct a phase contrast image based on the first and second single data sets to correct for spatially-dependent background phase variations.
