Summary of the RapidArc commissioning tests. (according to Ling et al [13]) performed as monthly checks over a period of one year. The plot showed the dose output difference between readings in each uniform band from the average values for: test 0.1 (a dynamic IMRT field with a 0.5 cm slit at 4 different gantry positions); test 2 (seven different combinations of dose rate and gantry speed during a RapidArc delivery) and test 3 (four different combinations of MLC speed and dose rate during a RapidArc delivery). Recommended tolerance was ±2% for all tests. Images for tests 2 and 3 are corrected for the beam profile, rationing the band and the open field acquisitions.
