Claim 16:
17. The method according to claim 2, wherein step 1d) is accomplished by processing said acquired or bias-corrected signal decays on a pixel by pixel basis to obtain the best possible fit between them and a non-mono-exponential equation of the form:, S

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 k is a shape parameter of a gamma distribution that is associated with this function, and
wherein ϑ is a scaling parameter of a gamma distribution that is associated with this function, and
wherein a non-linear least-squares method is used to obtain a fit.
