Spectral Decomposition of a 4-Rank Tensor and Applications to Generalised Diffusion Tensor Imaging

Marta Morgado Correia^1,2, Guy B. Williams²

In this work we show how spectral decomposition of a 4-rank generalised diffusion tensor can be used to characterise brain structure, including the definition of two metrics of anisotropy that do not depend on the arbitrary choice of a normalising function and its parameters.
