Fig. 4.Panel 1-1: Unregistered LGE CMR image and associated hyper-enhanced regions marked by pink contour and LV and RV blood-pool centers marked by red dots; Panel 2-1: before registration (CD: 2.72 mm, ASD: 2.24 mm); overlaid unregistered LGE CMR image and features (from Panel 1-1) onto the bSFFP image showing the RV and LV blood-pools and their centers (marked by blue dots) and the LV myocardium (MC) marked on the bSSFP image (Note: The hyper-enhanced regions enclosed by pink contour erroneously appear over the LV blood-pool, not the LV myocardium, where they truly belong); Panel 1-2: overlaid LGE CMR image onto the bSSFP image following unsupervised rigid registration (CD: 2.56 mm, ASD: 2.20 mm); Panel 2-2: unsupervised affine registration (CD: 2.52 mm, ASD: 2.18 mm); Panel 1-3: supervised rigid registration (CD: 1.56 mm, ASD: 1.64 mm); and Panel 2-3: supervised affine registration(CD: 1.68 mm, ASD: 1.76 mm). (Note: The accurate overlay of the hyper-enhanced regions marked by the pink contour over the LV myocardium, as well as significantly improved LV and RV blood-pool center-to-center distance following supervised registration in Panel 1-3 and Panel 2-3).
