An attention residual u-net with differential preprocessing and geometric postprocessing: Learning how to segment vasculature including intracranial aneurysms

•This paper proposes automatically segmenting vasculature, including intracranial aneurysms, from 3DRA images with the need for “patient-specific” computational hemodynamics.•An attention residual U-Net with preprocessing and postprocessing is constructed.•We design multi-scale supervision to improv...
