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.
