We proposed a new technique that allows for the correction of DC artifact for any phase-cycled pulse sequence. The proposed method includes receiver phase unification and its reversal before and after the application of a usual DC artifact removal technique in the specifically phase-cycled pulse sequence. Results show complete removal of the DC artifact for phase cycling angles of 0, 90, 180, 270 in the phase-cycled bSSFP sequence, and provides useful insight for the application of DC artifact removal in other phase-cycled pulse sequences.
