PROCESSING OF BRAIN IMAGE DATA TO ASSIGN VOXELS TO PARCELLATIONS

A method ( 400 ) including: determining ( 702 ) a registration function [ 705 , Niirf(T1)] for the particular brain in a coordinate space, determining ( 706 ) a registered atlas [ 708 , Ard(T1)] from the registration function and an HCP-MMP1 Atlas ( 102 ) containing a standard parcellation scheme, performing ( 310, 619 ) diffusion tractography to determine a set [ 621 , DTIp(DTI)] of brain tractography images of the particular brain, for a voxel in a particular parcellation in the registered atlas, determining ( 1105, 1120 ) voxel level tractography vectors [ 1123 , Vje, Vjn] showing connectivity of the voxel with voxels in other parcellations, classifying ( 1124 ) the voxel based on the probability of the voxel being part of the particular parcellation, and repeating ( 413 ) the determining of the voxel level tractography vectors and the classifying of the voxels for parcellations of the HCP-MMP1 Atlas to form a personalised brain atlas [ 1131 , PBs Atlas] containing an adjusted parcellation scheme reflecting the particular brain (Bbp).
