Fig. 2.
The top panel shows simulated ODFs for crossing fibers with rotating 2nd fiber (0°, 30°, 60°, 90°). The ODFs were simulated with two tensors at b=2500 s/mm2 and each has axial diffusivity of 1200 mm2/s and radial diffusivity of 250 mm2/s. The middle panel shows magnitude components of SH coefficients. The bottom panel shows phase components of SH coefficients. l and m are orders of Legendre function in the spherical harmonic bases; and SH coefficients of l = 0 to 4 and m = −l to l are shown here.
