http://www.nitrc.org/forum/forum.php?forum_id=9675 The atlas covers supra- and infra-tentorial regions and contains hierarchical segmentation levels created by a fusion of vascular and classical anatomical criteria. This deformable 3D digital atlas allows automatic and reproducible exploration of large-scaled data. In this version, the following images are provided or updated. * Images in “Atlas” folder are in MNI coordinates in 181x217x181 mm^3 * Images in “Atlas_182” folder in MNI coordinates in 182x218x182 mm^3 (compatible with FSL) * Image descriptions: ArterialAtlasLabels.txt: the “lookup table”. It contains the labels (descriptive and acronyms) for the regions defined in ArterialAtlas.nii and ArterialAtlas_level2.nii. ArterialAtlas.nii: Image defining 30 arterial territories and ventricles. The intensities of the parcels correspond to their labels IDs, listed in the lookup table “ArterialAtlasLabels.txt ArterialAtlas_level2.nii: The combination of ArterialAtlas.nii parcels in 4 major territories (ACA, MCA, PCA, VB). The intensities of the parcels correspond to their labels, listed in the ArterialAtlasLabels.txt ProbArterialAtlas_average.nii: 4D image of the arterial territory maps, calculated by averaging of lesion masks. Each dimension represents the probability of a voxel to belong to a certain vascular territory (ACA, MCA, PCA, VB, respectively). ProbArterialAtlas_BMM.nii: 4D image of the arterial territory maps, calculated by the Bernoulli Mixture Model(BMM) method. Each dimension represents the probability of a voxel to belong to a certain vascular territory (ACA, MCA, PCA, VB, respectively). BorderZone_ProbAve.nii: 4D image showing the ratio of average probability maps; first dimension is MCA / ACA, second dimension is MCA / PCA. TerritoryVoxels_BMM.nii: 3D image showing the assignment of voxels to major vascular territories, calculated through the variation in BMM µmax. The image intensities are: 1. ACA, 2. MCA, 3. PCA, 4. voxels attributed to more than one vascular territory, 5. voxels not attributed to any vascular territory. en-us Copyright 2000-2026 NITRC OSI Sat, 11 Apr 2026 8:03:37 GMT http://blogs.law.harvard.edu/tech/rss NITRC RSS generator
