Sparse solution of fiber orientation distribution function by diffusion decomposition. [PDF]
Fiber orientation is the key information in diffusion tractography. Several deconvolution methods have been proposed to obtain fiber orientations by estimating a fiber orientation distribution function (ODF).

Modelling white matter with spherical deconvolution: How and why? [PDF]
Since the realization that diffusion MRI can probe the microstructural organization and orientation of biological tissue in vivo and non-invasively, a multitude of diffusion imaging methods have been developed and applied to study the living human brain.

Artificial intelligence in corticospinal tract segmentation using constrained spherical deconvolution. [PDF]
Background: Tractography of cerebral white matter tracts is a technique with applications in neurosurgical planning and the diagnosis of neurological diseases. In this context, the approach based on the constrained spherical deconvolution (CSD) algorithm allows for more efficient and plausible segmentations.

A Fiber Tracking Algorithm Based on Non-Local Constrained Spherical Deconvolution
Fiber tracking with diffusion magnetic resonance imaging provides a powerful tool for non-invasive observation of white matter in the brain. Constrained spherical deconvolution (CSD) is a multi-fiber tracking model, which can model the orientation of ...

A Reversible Jump MCMC in Bayesian Blind Deconvolution With a Spherical Prior
Blind deconvolution (BD) is the recovery of a scene of interest convolved with an unknown impulse response function. Within a Bayesian context, prior distributions are assigned to both unknowns to regularize the BD problem. A common approach is to use Gaussian priors. Nonetheless, the latter do not alleviate the so-called scale ambiguity that prevents

$E(3) \times SO(3)$-Equivariant Networks for Spherical Deconvolution in Diffusion MRI [PDF]
We present Roto-Translation Equivariant Spherical Deconvolution (RT-ESD), an $E(3)\times SO(3)$ equivariant framework for sparse deconvolution of volumes where each voxel contains a spherical signal. Such 6D data naturally arises in diffusion MRI (dMRI),

Fiber Continuity Based Spherical Deconvolution in Spherical Harmonic Domain [PDF]
The reliable estimation of fiber orientation distributions from diffusion-sensitized magnetic resonance imaging is an important processing step for revealing structural connectivity in the human brain. Fiber orientation distributions are usually represented in spherical harmonic (SH) domain, but many modern spatial regularization techniques were not ...
