Assignee: STEPHAN MAIER
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 18:
19. 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(b)=S0exp(−(bD)α)

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 D is a parameter for a diffusion coefficient, and
wherein α is a stretching parameter, and
wherein a non-linear least-squares method is used to obtain a fit.
