Abstract To explore applications of image analysis in complex system’s performance evaluation and quantity traceability, the film dosimetry system for radiation therapy quality assurance (QA) is studied. Film dosimetry by dose-gray curve, plan data extraction by parsing certain DICOM files and parameters calculation such as Gamma by image analysis are realized, respectively. The algorithms of radiation therapy QA for intensity-modulated radiation therapy (IMRT) are developed. The proposed method can not only be suit for verification of IMRT, but also be used as reference to complex system’s performance evaluation based on image analysis.
