Conventional whole heart cine scan requires multiple breath-holds, and the prolonged scan time may limit its clinical use. We propose a highly accelerated whole heart real-time cine technique that combines AuTO-calibrated Multiband (MB) Imaging and Compressed Sensing (ATOMICS). With specially designed temporal phase modulation and in-plane undersampling pattern, single-band reference images can be extracted from the multiband data themselves, and cine images can be reconstructed using the CS framework. The proposed technique was demonstrated on a healthy volunteer with 16-fold acceleration (MB=2, undersampling factor=8), and free-breathing whole heart cine with diagnostic quality was acquired in about 12 seconds.
