We present a Bayesian probabilistic model to estimate the atlas of the brain white matter characterized by orientation distribution functions (ODFs) derived from HARDI. We employ the framework of large deformation diffeomorphic metric mapping and assume that the HARDI atlas is generated from a known hyperatlas through a flow of diffeomorphisms. We represent the shape prior of the HARDI atlas and the diffeomorphic transformation of individual observations relative to the atlas using centered…

Using Automatic HARDI Feature Selection, Registration, and Atlas Building to Characterize the Neuroanatomy of Aβ Pathology
TLDR
This paper proposes an automatic HARDI feature selection algorithm which is based on registering HARDi features to feature atlases for optimal clinical usability in population studies and applies this framework to the characterization of beta-amyloid pathology for the early detection of Alzheimer’s disease.
A Method for Automated Classification of Parkinson’s Disease Diagnosis Using an Ensemble Average Propagator Template Brain Map Estimated from Diffusion MRI
TLDR
This paper derived structural biomarkers from diffusion MRI (dMRI), a structural modality that allows for non-invasive inference of neuronal fiber connectivity patterns and presents the use of a manifold-valued feature called the Cauchy deformation tensor (CDT), which facilitates morphometric analysis and automated classification of a PD versus a control population.
Statistical modelling of high order tensors in diffusion weighted magnetic resonance imaging. (Modélisation statistique de tenseurs d'ordre supérieur en imagerie par résonance magnétique de diffusion)
TLDR
Fourth order tensors (T4) were used to model DW-MRI data and the problems of group comparison or individual against a normal group were discussed and solved using statistical analysis on T4s.

TLDR
It is shown that various orientation PDF processing operations, such as filtering, interpolation, averaging and principal geodesic analysis, may be posed as optimization problems on the Hilbert sphere, and can be solved using Riemannian gradient descent.
White matter atlas generation using HARDI based automated parcellation
