To verify the fluence distribution and number of monitor units for dynamic treatment techniques each patient treatment plan is applied to a measuring device before first treatment. We verify Rapid Arc treatment plans patient oriented using the IMRT-MatriXX (IBA, Schwarzenbruck, Germany). Therefore we generated a verification protocol. 3 patients with cerebral metastasis, 2 patients with head and neck cancer, and 5 patients with prostate cancer receiving Rapid Arc radiotherapy were included in this study. It is poss-ible to verify the 2D fluence distribution and the number of monitor units of Rapid Arc treatment plans using IMRT-MatriXX within a few minutes. Therefore we recommend the use of the IMRT-MatriXX for Rapid Arc treatment plans in the clinical routine.
