An extension of the tensor approach to the double wave-vector experiment for multiple concatenations is presented aiming at the examination of microscopic anisotropy in tissue for fully restricted diffusion. A detailed analysis of the generalized tensor expression to the fourth order does not only hold for the characterization of arbitrary pores in an idealized environment but can still derive a microscopic anisotropy measure on the pore size level with sufficient accuracy for timing parameters compatible to whole-body MR systems. Monte Carlo simulations confirm the theoretical considerations.
