(A-C;E-G): The flowchart of the 4D point-to-point registration framework. Note that the high-intensity patch inside the dotted line on the DE-MRI intensity model coincided well with the low voltage area on the 4D registered voltage map, but not on the 3D one. (G): the linear regression results of DE-MRI-derived voltage map and electroanatomic mapping. (D,H): the ROC curves of the DE-MRI-derived voltage map for the detection of low voltage areas of <0.6 mV and <0.1 mV, respectively.
