"Estimating Neuronal Fiber Organizations from Diffusion MRI"

Abstract: Diffusion MRI is an in vivo and non invasive imaging technology that uses water diffusion  as a proxy to probe  architecture of biological tissues. Diffusion MRI  has been widely used in white matter fiber tracts reconstruction as well as many clinical  applications.

In this talk, We discuss various models for estimating local (voxel-wise) neuronal fiber organizations which are then used as inputs in tracking algorithms to reconstruct fiber tracts. We focus on their capability to resolve crossing fibers -- a major challenge in diffusion MRI.  We also consider spatial smoothing schemes to leverage information from neighboring voxels.  These methods are illustrated through both synthetic experiments and diffusion MRI data from large brain imaging  consortium.
