Abstract
Diffusion Tensor MR Imaging (DTI) provides non-invasive approach to track white matter (WM) trajectories within human brain in vivo, and thereby facilitates studies of anatomical connectivity between sub-cortical and cortical regions. This paper presents a probabilistic fiber tracking framework, which aims to address the two problems in earlier approaches: first, it does not adopt fractional anisotropy (FA) as the stopping criteria so that the exploration of cortico-cortical connectivity is feasible; secondly, fiber tracking process is regularized so that trajectory with low curvature means high belief of connection between two voxels.
