In diffusion MRI, biophysical models offer a non-invasive means of probing the tissue micro-architecture of the human brain. However, most models rely on closed-form formulas derived with simplifying assumptions such as short gradi- ent pulse, Gaussian phase distribution, and the absence of compartmental ex- change. We present a fast microstructure fingerprinting framework for accurate estimation of axon/soma radii and membrane permeability without relying on these assumptions.
