SENSE combined compressed sensing technique is applied to multi-slice cardiac CINE imaging with breath holds. As to the compressed sensing, ITSC is used, which truncates small transformed coefficients in r-f domain to make data sparse, and it restores the measured data in k-t domain iteratively until the reconstructed images converge. Variation of ejection fraction (EF) is measured for two set of experiments, one from regenerated data set by resampling the original data set, and the other from real measurements. Using the variation of EF and normalized mean square error clinical usefulness of the technique is demonstrated.
