This study develops a spiral-in/out bSSFP pulse sequence combined with a low rank plus sparse (L+S) reconstruction method for free-breathing ungated high resolution real-time cine with whole heart coverage. Within 30 seconds, this proposed method achieves total ten slices spiral cardiac movies with an in-plane 1.37 x 1.37 mm² spatial resolution and 40 ms temporal resolution.
