A RMSE (root mean square error) comparison of parameter estimation methods using synthetic DKI dataset. Five levels of noise were added. Estimation methods either without (upper) or with (lower) constraints were respectively compared. The RMSE of the resulting ADC (left) and AKC (right) maps showed that our three AIS methods (UAIS, CAIS and SCAIS) provided similar or better results compared to conventional methods. In particular, SCAIS performed the best. (Refer to Table 1 for abbreviations of the methods.)
