We describe a method to classify the complexity of water diffusion in tissue, or tissue structure, from high angular resolution diffusion weighted O W ) MR measurements. We fit the series of even order spherical harmonics (SHs) to the measured data and use an ANOVA deletion of variables test to determine at what order the series can be truncated. The level of truncation indicates whether the diffusion at each voxel is isotropic, anisotropic Gaussian or non-Gaussian. Clusters of non-Gaussian… CONTINUE READING
