Summary of the registration convergence and reliability for the affine and B-spline registration stages. Success rate corresponds to the portion of the experiments that led to successful registration based on Dice similarity coefficient (DSC) and Landmark registration error (LRE) measures. 95% capture range corresponds to the maximum initial mis-alignment that led to successful completion of 95% of the registration experiments.
