Computational Representation of White Matter Fiber Orientations
Figure 2
(a) Examples of synthesized noisy diffusion profiles, with Rician noise level (). The red lines indicate the fiber directions used in the simulations. (b) Reconstructed fiber profiles from the simulated diffusion profiles in (a). The colored lines indicate the estimated fiber directions using mixtures of vMF distributions. The -values used in the simulations were , and the angles between crossing fibers were [90°, 90°, 50°, 60°, 50°] (from left to right).
