http://pipeline.loni.usc.edu/ Splet01. feb. 2014 · MATERIALS AND METHODS: Twenty patients, candidates for excision of epileptogenic lesions, were subjected to higher-angular resolution diffusion imaging–based fiber tractography. Seed points were created without manual bias, predominantly by FreeSurfer and voxel-based atlases. We focused on 2 important fiber bundles, namely the …

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, … SpletSurface seeding is a way to generate initial position for tractography from cortical … tace allen physio https://melodymakersnb.com
