wherein, in this equation, S0 is a constant that depends on constant values associated with (a) the magnetic imaging apparatus, (b) the spin-spin relaxation time T2, (c) the spin lattice relaxation time T1, and (d) the spin density ρ,
wherein b is the diffusion encoding level, preferably determined for each pixel location, and
wherein ADCK is a parameter for the apparent kurtosis diffusion coefficient, and
wherein, K a parameter for the excess kurtosis, and
wherein a non-linear least-squares method is used to obtain a fit.
