Influence of PSF mismatch (A), registration mismatch (B), and background heterogeneity (C) on the performances of PVC methods for a TBR of 12. A Kidney RC bias (averaged over the 6 kidneys) with respect to PSF mismatch (± 6 mm, 2 mm step, upper panel) and S:V ratio (4 mm PSF error, lower panel). B Kidney RC bias with respect to registration mismatch (1, 2 and 3 voxel sizes translations). C Kidney RC bias with respect to background heterogeneity (heterogeneity ratio ranging from 1 to 4 with 0.25 step, upper panel) and S:V ratio (heterogeneity ratio of 3, lower panel)
