Axon size is an important parameter which affects
conduction velocity in neuronal tissues. Recently
angular d-PFG MR experiments were used to obtain
microstructural information in different neuronal
tissues. Since in many cases the ground truth of the
studied samples is not known a priori, other and we have
used microcapillaries phantoms of different complexity
to challenge the microstructural information that can be
obtained by modeling the signal in different NMR
experiments. In the present study, we tried to evaluate
simultaneously the size and direction of such systems
from angular d-PFG NMR experiments.
