We suggest an improved fitting algorithm for Brain white
matter microstructure models to extract parameters like
axon radius, fiber orientation and volume fractions of
different compartments. Suggested is fast and accurate
as compared to traditional techniques. Further, it does
not simplify or linearize model to extract the
information.
