Score (a) and rank (b) comparisons of k-t PCA and k-t SLR reconstruction results with and without motion compensation by 2 experienced cardiologists. Four bars in each plot from left to right correspond to k-t PCA and k-t SLR without motion compensation, k-t PCA and k-t SLR with motion compensation. The scale of the scores range from 1 (very poor) to 5 (very good) and the scale of the ranks range from 1st to 4th. Error bars indicate the standard deviation, and * indicates significance at p < 0.05
