  1. Techniques with different beam configurations were compared with regard to plan metrics. The deviation of monitor units (MU), delivery time (T) and Paddick Conformity Index (CI) were calculated between each plan version and the reference plan (V2C15). For all patients, the mean and standard deviation are shown for comparisons #1–7
