FIG. 2.

Comparison of tractography results of FATCAT 3dTrackID in different modes: (A) deterministic (DET), (B) miniprobabilistic (MINIP), and (C) fully probabilistic (PROB). AND-logic connections are shown for a network of targets (gray) using either tracts colored by local orientation in (A, B) or probabilistic volumes shown as green surfaces in (C). The yellow and orange arrows highlight single-fiber connections between pairs of targets using the DET mode; in the MINIP results, the former appears to be reinforced by the repeated uncertainty-based tracking, while the latter remains an outlier. This is verified by comparison with the PROB results and suggests the increased robustness of the MINIP method compared with DET. Color images available online at www.liebertpub.com/brain
