Figure 5.

Reproducibility of simulated axon damage. Plots A–D show the 10^th, 50^th, and 90^th percentile isosurfaces of the motion-probability propagators estimated in each of the 25 repetitions. Nested surfaces are constructed so that local color and position of vertices indicate the distance corresponding to the indicated quantile of the probability of motion along the each direction. Repetitions of each set of surfaces are nearly identical, so the isosurfaces from the separate repetitions are difficult to distinguish except as slightly blurred lines. The spatial scales for the figures corresponding to the two diffusion times are constant across panels but are different from each other. Quantitative comparisons of the mean PSNR are shown for radial distance (E) and angular orientation (F).
