TL;DR: The encouraging finding that most state-of-the-art algorithms produce tractograms containing 90% of the ground truth bundles (to at least some extent) is reported, however, the same tractograms contain many more invalid than valid bundles, and half of these invalid bundles occur systematically across research groups.
Journal ArticleDOI
Dipy, a library for the analysis of diffusion MRI data
Eleftherios Garyfallidis,Eleftherios Garyfallidis,Matthew Brett,Bagrat Amirbekian,Ariel Rokem,Stefan van der Walt,Maxime Descoteaux,Ian Nimmo-Smith +7 more
TL;DR: Dipy aims to provide transparent implementations for all the different steps of dMRI analysis with a uniform programming interface, and has implemented classical signal reconstruction techniques, such as the diffusion tensor model and deterministic fiber tractography.
Journal ArticleDOI
QuickBundles, a Method for Tractography Simplification
Eleftherios Garyfallidis,Eleftherios Garyfallidis,Matthew Brett,Marta M Correia,Guy B. Williams,Ian Nimmo-Smith +5 more
TL;DR: A simple, compact, tailor-made clustering algorithm, QuickBundles (QB), that overcomes the complexity of these large data sets and provides informative clusters in seconds and can help in the search for similarities across several subjects.
Journal ArticleDOI
Tractometer: towards validation of tractography pipelines.
Marc-Alexandre Côté,Gabriel Girard,Arnaud Boré,Eleftherios Garyfallidis,Jean-Christophe Houde,Maxime Descoteaux +5 more
TL;DR: Overall, it is shown that averaging improves quality of tractography, sharp angular ODF profiles helps tractography and deterministic tractography produces less invalid tracts which leads to better connectivity results than probabilistic tractography.
Journal ArticleDOI
Recognition of white matter bundles using local and global streamline-based registration and clustering.
Eleftherios Garyfallidis,Marc-Alexandre Côté,François Rheault,Jasmeen Sidhu,Janice Hau,Laurent Petit,David Fortin,Stephen Cunanne,Maxime Descoteaux +8 more
TL;DR: The purpose of the proposed method, named RecoBundles, is to segment white matter bundles and make virtual dissection easier to perform and robust and adaptive to incomplete data and bundles with missing components.
