Towards non-parametric fiber-specific relaxometry in the human brain
A. Reymbaut, J. Critchley, G. Durighel +4
Purpose: To estimate fiber-specific values, i.e. proxies for myelin content, in heterogeneous brain tissue. Methods: A diffusion- correlation experiment was carried out…
Matrix moments of the diffusion tensor distribution
A. Reymbaut
Purpose: To facilitate the implementation/validation of signal representations and models using parametric matrix-variate distributions to approximate the diffusion tensor distribu…
Resolving orientation-specific diffusion-relaxation features via Monte-Carlo density-peak clustering in heterogeneous brain tissue
A. Reymbaut, J. P. de Almeida Martins, C. M. W. Tax +3
Characterizing the properties and orientations of sub-voxel fiber populations, although essential to study white-matter architecture, microstructure and connectivity, remains one o…
Magic DIAMOND: Multi-Fascicle Diffusion Compartment Imaging with Tensor Distribution Modeling and Tensor-Valued Diffusion Encoding
A. Reymbaut, A. Valcourt Caron, G. Gilbert +5
Diffusion tensor imaging provides increased sensitivity to microstructural tissue changes compared to conventional anatomical imaging but also presents limited specificity. To tack…
Mott transition and high-temperature crossovers at half-filling
A. Reymbaut, M. Boulay, L. Fratino +4
The interaction-driven Mott transition in the half-filled Hubbard model is a first-order phase transition that terminates at a critical point in the t…
