The framework of the iBEAT V2.0 computational pipeline. The framework includes an image segmentation component: (a) Input inhomogeneity-corrected T1w image (also applicable to T2w images, or both), (b) T1w image after skull stripping and cerebellum removal, and (c) Tissue segmentation map, with green indicating gray matter, white indicating white matter, and blue indicating cerebrospinal fluid; and a cortical surface reconstruction component: (d) Left/right hemisphere separation and filling of the noncortical regions with white matter, (e) Topology correction of white matter volume, (f) Reconstructed inner and outer cortical surfaces represented by triangular meshes, (g) Color-coded derived representative cortical properties, e.g., mean curvature, sulcal depth, local gyrification index, and cortical thickness, and (h) Parcellated cortical surfaces based on Desikan scheme.
