Optimal Short-Time Acquisition Schemes in High Angular Resolution Diffusion-Weighted Imaging

Table 4

Söderman’s model without added noise, with tolerance: 0.5°. The table presents the optimal combination of -value (s/mm2) and -order together with the detected angular error (°) for each combination of simulated angle and number of gradients.
