Inconsistency and target registration error (TRE) for registration loops in four-dimensional (4-D) liver MRI sequences. Each point indicates the inconsistency of one loop of three registrations and the average TRE of those three registrations, and the blue line is a least-square fit with $r=0.77$ denoting the Pearson correlation. For more details on the data and registration algorithms, please see Sec. 4.4.
