Figure 8

Bootstrap and simulation coincidence angle maps for the ROI are shown. The coincidence map from the bootstrap analysis (200 samples and 6 averages) of actual data using the gradient scheme ‘original 6′ (a) is in good agreement with simulation results for the same scheme (b). Simulations show the maps of coincidence angle for other gradient schemes: ‘rotated 6′ (c), ‘original 12′ (d), ‘original 21′ (e) and ‘original 92′ (f). Coincidence angles vary as low-resolution gradient vector sets are rotated (compare b and c). As angular resolution improves, however, coincidence angles converge (d-f).
