摘要: Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, model can only resolve single orientation within each imaging voxel. New emerging have been proposed obtain better representation diffusion process occurring in crossing. In this paper, we adapt algorithm q-ball representation, which results spherical Radon transform high angular resolution data. This is based Monte-Carlo strategy, using regularized particle trajectories sample white matter geometry. The method validated phantom bundle crossing made up haemodialysis fibers. also applied detection auditory tract three human subjects.
