Abstract

To compare two different dosimetric systems namely EDR2 film and MatriXX Evolution for Intensity Modulated Radiation Therapy (IMRT) patient specific quality assurance (QA). The Treatment Planning System (TPS) calculated dose distributions were compared with measured dose distributions using both EDR2 film and MatriXX Evolution for nine IMRT patients. The spatial difference in the dose distribution (Distance- To-Agreement) and the dose deviation (Delta-Dose) were verified with the Gamma Index Method. The tolerance of 3% dose difference and 3mm DTA was set for the analyses. The results were analyzed statistically using paired, two-tailed Student t-test and P< 0.01 is kept as a threshold for the significance level.
