TOP-BRAIN: CTA and MRA anatomy
A collection of paired CTA and MRA volumes with the major intracranial vessels annotated on voxel-wise basis.
Cases and segmentations are taken directly from the TOP-BRAIN dataset (TopBrain Segmentation Challenge for Whole Brain Vessel Anatomy), which is distributed under a license requiring source attribution. This dataset contains voxel annotations for over 40 landmark brain vessel anatomies covering both arteries and veins.
