Splet01. jun. 2016 · Of the two tractography seeding strategies used, the unidirectional surface-to-surface method, producing dDT1, had a slight performance advantage over the bidirectional voxel-to-surface (dDT3) method. Relative to a geometrically predicted streamline bias, dDT1 showed a bias similar in magnitude, but different in spatial pattern, …

SpletTractography Analysis with QIT. This page provides a tutorial for doing tractography with QIT.
