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.

Sparse Reconstruction Challenge for diffusion MRI: Validation on a physical phantom to determine which acquisition scheme and analysis method to use?

TL;DR: The SPArse Reconstruction Challenge (SPARC) was held along with the workshop on Computational Diffusion MRI to validate the performance of multiple reconstruction methods using data acquired from a physical phantom to provide appropriate guidelines to neuroscientists on making an informed decision while designing their acquisition protocols.

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
A unified framework for multimodal structure-function mapping based on eigenmodes
TL;DR: A unified computational framework is proposed that generalizes recently proposed structure-function mappings based on eigenmodes and shows how they can be obtained by specific choices of the parameters of this framework by applying to 50 subjects of the Human Connectome Project.
Journal ArticleDOI
Sampling Signals With a Finite Rate of Innovation on the Sphere
TL;DR: This work shows that a particular class of non-bandlimited signals, which have a finite rate of innovation, can be exactly recovered using a finite number of samples, and designs an optimal sampling kernel that achieves accurate reconstruction of the signal using only 3K samples.
