Numerous different models provide detailed microstructure information from diffusion MRI data. In order to challenge them, there is a need for complex phantoms with known structural characteristics. For this purpose, we present a novel phantom, consists of spherical fixed yeast cells and cylindrical microcapillaries. Despite of its complexity, arising from the different size, geometry and size distribution of the restricted compartments, there is a good correlation between the known ground truth and the features that were extracted from fitting single diffusion encoding (SDE) MRI experimental data, assuming continued or discrete weight of size distribution.
