Banding artifacts in bSSFP sequences pose a challenge in cardiac cine imaging, especially at 3.0T. Recently, a “Geometric Solution” (GS) which is capable of completely removing banding artifacts has been introduced and demonstrated in applications outside the heart. This work investigates the feasibility of extending GS to cardiac cine imaging at 3.0T and explores its potential to enable longer TRs than have conventionally been feasible with bSSFP, permitting sub-millimeter resolution cine imaging free of banding artifacts.
