A Generalized Diffusivity for Tuning Diffusion-Weighted Imaging Contrast

Mariana Lazar¹, Jens H. Jensen¹, Joseph A. Helpern¹

In this abstract we introduce a new measure, the generalized diffusivity, to characterize diffusion in biological tissues. The generalized diffusivity include a tuning parameter,α , that allows differential weighting of diffusion paths on different length scales. For α=2, the generalized diffusivity reduces to the conventional mean diffusivity.
