Phantom Fiber Length Results. (A) Example fiber tracking and the mean number of streamlines are represented for each reconstruction method in the Fibercup phantom. Fiber tracking with the DTI reconstruction was unable to detect any streamlines that navigated both crossings. (B) Distribution of streamline length estimates for each reconstruction method. GQI reconstructions produced longer and less variable streamline estimates compared to the ball-and-sticks model (BSM 0.01, BSM 0.03). (C) To quantitatively evaluate length estimates, the streamline lengths were multiplied by the probability. Each reconstruction method yields significantly different modal streamline length estimates relative to each other reconstruction method. DTI, diffusion tensor imaging; GQI, generalized q-sampling imaging; decon, deconvolution; M, mean; BSM, ball-and-sticks model. *Significance of at least p < 0.05.
