为探索图像分析在复杂系统性能评价和计量溯源方面的应用，研究了放疗胶片剂量验证系统性能评价方法，实现了胶片数据剂量转换、DICOM 文件解析提取计划数据、图像分析比较提取 Gamma 参数等，开发和实现了调强放疗验证分析的算法。提出的方法不仅可与调强放疗设备配套使用，而且对基于图像分析的复杂系统性能评价具有借鉴意义。

To ezplore applications of image analysis in complez 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 eztraction 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 complez system’s performance evaluation based on image analysis.
