Patent ID: 8558547

Claim:
A non-transitory computer readable storage medium for radio-frequency (RF) field mapping using a processor, the non-transitory computer readable storage medium including instructions to command the processor to: encode a B 1 phase in at least one magnetic resonance (MR) excitation pulse as an encoded B 1 phase MR excitation pulse for at least a subset of a plurality of transmit channels within a magnetic resonance imaging (MRI) system; encode a B 1 magnitude in at least one off-resonance MR pulse as an encoded B 1 magnitude off-resonance MR excitation pulse for at least a subset of the plurality of transmit channels within the MRI system; and determine one or more composite B 1 fields resulting from a transmission of the at least one encoded B 1 phase MR excitation pulse and the at least one encoded B 1 magnitude off-resonance MR pulse.
