- Аннотация: Diffusion tensor imaging is a well-known and well-established imaging technique. It allows one to easily visualize the neuronal tissue architecture by using the eigenvector linked to the largest eigenvalue of the diffusion tensor. However, the diffusion tensor eigenvectors form a complete orthonormal basis in space and contain additional information. We hypothesize here that all three eigenvectors in the neuronal bundles can generate a structure similar to a crystal lattice and keep this configuration along the bundle with high anisotropy. Thus, vector fields based on secondary and/or tertiary eigenvectors could improve the segmentation/reconstruction of fibre tracts and provide additional information on white matter organisation.
