Several anomalous diffusion models, both
empirical and theoretical, were proposed to explain the departure from
purely mono-exponential decay of DWI signal in biological tissues. Recently, a
fractional motion (FM) based diffusion MRI theory was proposed, which was
claimed to be a proper model in the description of diffusion processes in
biological systems. However, the tensorial properties of FM related parameters
is still unknown. In this work, diffusion magnetic field gradients were applied
in several non-linear directions to acquire DWI images. Then, the FM-based
parameters were obtained in each diffusion direction and found direction dependent.
