%description
An implementation of a taxonomy of models of restricted diffusion in
biological tissues parametrized by the tissue geometry (axis, diameter,
density, etc.). This is primarily used in the context of diffusion
magnetic resonance (MR) imaging to model the MR signal attenuation in the
presence of diffusion gradients. The goal is to provide tools to simulate
the MR signal attenuation predicted by these models under different
experimental conditions. The package feeds a companion 'shiny' app
available at <https://midi-pastrami.apps.math.cnrs.fr> that serves as a
graphical interface to the models and tools provided by the package.
Models currently available are the ones in Neuman (1974)
