bSSFP parameter optimization for 0.55 T. (a) Simulations and (b) healthy subject imaging demonstrating parameter optimization for bSSFP cine imaging at 0.55 T by varying flip angle and receiver bandwidth (rBW). Simulated SNR and CNR are scaled relative to simulated 1.5 T SNR and CNR for our standard cine protocol. The yellow dots in (a) and yellow frame in (b) demonstrate the selected parameter combination
