Table 1.

Summary of the setup errors on the 240 CBCT scans of different treatment fractions of six patients. Both translational and rotational errors are presented. For each catalog, we calculate the ensemble mean ± SD, 95% CI, the proportion of the testing fractions within a predefined clinically accepted tolerance (±3mm/±2º), and CC.
