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.
