A novel retrospectively-gated reconstruction approach is proposed for accelerated cardiac cine imaging. The approach combines advantageous features from fast-imaging methods such as GRAPPA, SPACE-RIP, UNFOLD, kt-SENSE, SHRUG and GEYSER. The result is a reliable algorithm, tested up to acceleration factors of 6.3 (subsampling factor of 8), and featuring fast reconstruction processing.
