While most current double PFG methods concentrate on
parameterization of new types of anisotropies in gray
matter, we provide here a simple and intuitive filtered
tensor based framework to explore the utility of double
PFG for mapping white matter. The preliminary results
shown here suggest that using filtered tensors has the
potential to resolve complex fiber architecture in an
intuitive, signal driven way, which is different than
the typically complex model based HARDI methods.
