diffusion-relaxation MRI data from biomimetic phantoms

We provide diffusion-relaxation MRI data and methods for estimating the inner fibre radius of biomimetic phantoms 🎁.

Scanning Electron Micrographs depicting the microscopic morphology of the biomimetic phantoms. All phantom samples are shown using the same length scale. Phantom1 and Phantom2 are displayed together as both were built using similar distributions of inner fibre radii.

Run the Matlab code to replicate the figures reported in the paper. We provide the raw diffusion-relaxation data (spherical mean signal) to facilitate future evaluations and developments.

Implementation of the algorithms described here: 📢
