Random Action of Compact Lie Groups and Minimax Estimation of a Mean Pattern [PDF]
, 2011 This paper considers the problem of estimating a mean pattern in the setting of Grenander's pattern theory. Shape variability in a dataset of curves or images is modeled by the random action of elements in a compact Lie group on an infinite dimensional ...

Generalized Richardson-Lucy (GRL) for analyzing multi-shell diffusion MRI data
NeuroImage, 2020 Spherical deconvolution is a widely used approach to quantify the fiber orientation distribution (FOD) from diffusion MRI data of the brain. The damped Richardson-Lucy (dRL) is an algorithm developed to perform robust spherical deconvolution on single ...

How does B-value affect HARDI reconstruction using clinical diffusion MRI data? [PDF]
PLoS ONE, 2015 A number of imaging factors can affect the orientation distribution function (ODF) reconstruction in high angular resolution diffusion imaging (HARDI). The aim of this study was to investigate the effect of the b-value on the HARDI reconstruction and to ...

Improved sensitivity to cerebral white matter abnormalities in Alzheimer's disease with spherical deconvolution based tractography. [PDF]
PLoS ONE, 2012 Diffusion tensor imaging (DTI) based fiber tractography (FT) is the most popular approach for investigating white matter tracts in vivo, despite its inability to reconstruct fiber pathways in regions with "crossing fibers." Recently, constrained ...

Near-Field Seismic Motion: Waves, Deformations and Seismic Moment
Axioms, 2022 The tensorial force acting in a localized seismic focus is introduced and the corresponding seismic waves are derived, as solutions of the elastic wave equation in a homogeneous and isotropic body. The deconvolution of the solution for a structured focal

Organization of the commissural fiber system in congenital and late-onset blindness
NeuroImage: Clinical, 2020 We investigated the effects of blindness on the structural and functional integrity of the corpus callosum and the anterior commissure (AC), which together form the two major components of the commissural pathways. Twelve congenitally blind (CB), 15 late

Tracking white-matter brain modifications in chronic non-bothersome acoustic trauma tinnitus
NeuroImage: Clinical, 2021 Subjective tinnitus is a symptom characterized by the perception of sound with no external acoustic source, most often accompanied by co-morbidities. To date, the specific role of white matter abnormalities related to tinnitus reaches no consensus in the
