摘　　要：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 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.
