Method and system for characterizing a spatial pattern for a microstructural property of a biological tissue

A computer-implemented method for characterizing a spatial distribution of a tissue microstructural property from quantitative imaging data, the method comprising

• acquiring, for a biological object and via a first interface, a property map for a tissue of the biological object, wherein the property map comprises voxels whose intensity represents a measured value V of the microstructural property for the tissue;
• determining, for at least a set of the voxels, a distance d separating each voxel of the set from a center of interest so that each voxel of the set is associated with a measured value V and a determined distance d;
• fitting, for the set of voxels, a function f to the measured values V expressed as a function of the determined distance d according to V(d)=f(β1, . . . , βN,d) in order to determine a set of fitting parameters;
• determining, from the fit, values of each fitting parameter;
• and
• outputting a value of at least one of the fitting parameters.
