Summary of the eigenvalues and the non-diffusion weighted image intensity, S ₀, used to generate the simulated image intensities for each voxel in the digital DTI phantom data

	λ1 [10−6 mm2/s]	λ2 [10−6 mm2/s]	λ3 [10−6 mm2/s]	S 0
WM	N(1300,150)	N(550,40)	N(550,40)	N(200,100)
GM	N(1000,100)	N(800,60)	N(660,50)	N(270,14)
CSF	N(3200,100)	N(3200,100)	N(3200,100)	N(900,45)

These values were set in accordance with the literature, and were added to values generated at random from the Normal distribution. N(a,b) indicates the normal distribution with mean a and standard deviation b
