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.
