Table 2 Systematic and random translational errors attributed to interfractional prostate motion (see Table 1) for a selection of studies (lines 2–4) in comparison to residual errors (line 5: estimated by the deviations between two measurement methods of prostate position) and errors by intrafractional prostate motion (line 6)
From: Appropriate patient instructions can reduce prostate motion
