Comparison of linear reconstruction and non-linear reconstruction for retrospective cine. (a) Segmented breath-held cine; (b) Retrospective cine using the non-linear SPIRiT; (c) Retrospective cine using the linear SPIRiT (equation 3). (d) Retrospective cine with only zero-filling. No parallel imaging is applied on the binned k-space. The insufficient performance of linear SPIRiT is improved by the non-linear regularization.
