Simultaneous multi-slice (SMS) imaging is an efficient MRI technique that better preserves SNR than conventional parallel imaging (PI). However, single-band images usually need to be acquired to provide references for slice-unaliasing, causing an untrivial scan time overhead in some scenarios. We extended a recently reported self-calibrated SMS imaging strategy based on RF phase modulation, and propose using gradient temporal modulation to achieve auto-calibrated SMS bSSFP, which avoids the bSSFP banding shift and is preferred in cardiac Cine due to its contrast and intrinsically high SNR. In-plane PI can also be incorporated with shared auto-calibration.
