We have introduced an automatic pipeline based on diffusion-weighted tractography for the reconstruction of four white-matter structures of interest. These anatomical reconstructions are visualized during brain tumour surgery to aid in the prevention of sensorimotor, visual and language deficits. The automatic tractography pipeline produces robust results, owing in part to the deep-learning based segmentation of brain regions which is robust to deformations of the brain due to brain shift, and the post-tractography filtering method which can remove spurious fibers.
