Diffusion MRI is arguably the method of choice for characterizing white matter microstructure
in vivo. Over the typical duration of diffusion encoding, the displacement of water molecules …

The biophysical modeling efforts in diffusion MRI have grown considerably over the past 25
years. In this review, we dwell on the various challenges along the journey of bringing a …

Diffusion magnetic resonance imaging (dMRI) tractography is currently the only imaging
technique that allows for non-invasive delineation and visualisation of white matter (WM) …

Phantoms, both numerical (software) and physical (hardware), can serve as a gold standard
for the validation of MRI methods probing the brain microstructure. This review aims to …

The brain is one of the most complex organs, and tools are lacking to assess its cellular
morphology in vivo. Here we combine original diffusion-weighted magnetic resonance (MR) …

Monte-Carlo Diffusion Simulations (MCDS) have been used extensively as a ground truth
tool for the validation of microstructure models for Diffusion-Weighted MRI. However …

To date, numerical simulations of the brain tissue have been limited by their lack of realism
and flexibility. The purpose of this work is to propose a controlled and flexible generative …

Abstract Background Monte Carlo simulations of diffusion are commonly used as a model
validation tool as they are especially suitable for generating the diffusion MRI signal in …

A GPU-based tool to generate realistic phantoms of the brain microstructure is presented.
Using a spherical meshing technique which decomposes each microstructural item into a …

The pore structure of expanded graphite (EG) including pore volume, pore size distribution
and surface area is investigated by mercury porosimetry, nitrogen adsorption and SEM …
