Efficient axon diameter distribution recovery with long diffusion time

We propose an original technique for measuring axon diameter distributions that simplifies the AxCaliber framework in complexity and shortens the acquisition time. In particular, we derive a new closed form expression describing the echo attenuation in the intra-axonal space. The method is validated using Monte-Carlo simulations of NMR signals from complex white matter-like environments. The results are promising and illustrate the potential of the method.
