Clinical brain diffusion imaging provides low angular resolution diffusion images that were up to now analyzed under the assumption of Gaussian diffusion. An important limitation of such an analysis is that it does not exhibit crossing fibers. In this abstract, a non-Gaussian diffusion profile is assumed that allows for the accurate estimation of crossing fibers from low angular resolution diffusion images.
