Abstract:
1. A method using an MRI device to extract m diffusion direction(s) μ j from N diffusion-weighted magnetic resonance signals S i of any part of a body that contains water molecules, wherein m is a predetermined positive number m of diffusion direction(s) μ j to be identified in each voxel of said body part with m≧1, comprising exposing by an emitter-receiver the body to a magnetic resonance imaging process, in which N magnetic field diffusion gradients q wherein using a calculator a first component modelling directional variability of water molecules displacements with diffusion direction μ wherein a sum of the first component and of the second component is calculated in the calculator for each of the m diffusion direction(s) μ wherein, for each of the m diffusion direction(s) μ
