A Bayesian Approach to Fiber Orientation Estimation Guided by Volumetric Tract Segmentation

Diffusion magnetic resonance imaging (dMRI) has enabled the reconstruction of white matter tracts by capturing the anisotropy of the water diffusion in tissue. In a basic dMRI strategy, diffusion tensor imaging (DTI) models the water diffusion as a diffusion tensor  (Basser et al., 1994). More advanced diffusion imaging techniques, such as high angular resolution diffusion imaging (HARDI) (Tuch et al., 2002) and diffusion spectrum imaging (DSI) (Wedeen et al., 2005), have been used to represent crossing fibers.
