The performance of the advanced fitting algorithm for an isotropic voxel (A) and an anisotropic voxel (B). ht = 4h was used for the anisotropic voxel. The performance was tested for a total of 25,200 combinations as described in the caption of Fig. 2. Data are presented in mean ± SD. Each point represents the mean and error for the combination of other parameters as in Fig. 2, but the error was too small to be seen.
