Voxel based morphometry (VBM) is an automated tool used to assess the topography and magnitude of cerebral atrophy from MRI scans. However, VBM output is highly dependent on the input provided by registration and segmentation algorithms. Diffeomorphic anatomical registration through exponentiated lie ...
2.2Voxel-based morphometry imaging Voxel-based morphometry(VBM) provides an automated, voxel-wise comparison of structure volumes between groups[31]. This procedure involves the normalization of all individual MRI scanning subjects to a standard anatomical space to remove inter-individual variations in bo...
