Polynomial models of the spatial variation of axon radius in white matter

Figure 2 This shows plots of ηT and ρ (estimated using both polynomial and voxel methods) in the region of interest, from the simulation experiment with |G|max=40mT/m Figure 3 The estimated values of ρ in the human CC using the polynomial fitting method (a) and the voxel method (b). The polynomial method extracts the low-high-low trend we expect to see. The voxel method fits reasonable values of ρ in the midbody, but wildly overand underestimates in the genu and splenium.
