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.

TL;DR: The results demonstrate fundamental ambiguities inherent to tract reconstruction methods based on diffusion orientation information, with critical consequences for the approach of diffusion tractography in particular and human connectivity studies in general.
Journal ArticleDOI
Structured sparsity for spatially coherent fibre orientation estimation in diffusion MRI.
Anna Auría,Alessandro Daducci,Alessandro Daducci,Jean-Philippe Thiran,Jean-Philippe Thiran,Yves Wiaux +5 more
TL;DR: The approach reconciles voxelwise sparsity and spatial regularisation and defines a spatially structured FOD sparsity prior, where the structure originates from the spatial coherence of the fibre orientation between neighbour voxels.
Journal ArticleDOI
Tensor optimization for optical-interferometric imaging
TL;DR: In this paper, a linear convex approach for tensor recovery with built-in supersymmetry was proposed, and the inverse problem was regularized through a nuclear norm relaxation of a low-rank constraint.
Proceedings ArticleDOI
Accelerated microstructure imaging via convex optimisation for regions with multiple fibres (AMICOx)
Anna Auría,David Romascano,E. Canales-Rodriguen,Yves Wiaux,T. B. Dirby,Daniel C. Alexander,Jean-Philippe Thiran,Alessandro Daducci +7 more
TL;DR: A flexible framework is presented, based on convex optimisation, that enables fast and accurate reconstructions of the microstructure organisation, not limited to areas where the white matter is coherently oriented and the ability of the method to correctly estimate the microStructure features in crossing regions is shown.
