Table 2 Overview of beam configurations and list of comparisons. Varying beam configurations are displayed on the left part: Single, double and two single arc types, full and partial arc length and different collimator positions were defined and used for comparison. The corresponding list of comparison between the different beam configurations is displayed on the right part
