From: Impact of the frequency of online verifications on the patient set-up accuracy and set-up margins
Interindividual variability of frequencies of set-up errors larger than 5 mm (three-dimensional vector). The frequency of online verifications is plotted on the horizontal axis (0%, no online verification; 20%, online verification once a week; 50%, online verification every other day), and the percentage of fractions with set-up errors larger 5 mm on the vertical axis.
