摘　　要：目的:实现CT和DICOM-RT四个放疗对象-RT-Structure、RT-Plan、RT-Image、RT-Dose在治疗计划系统(TPS)中的存储和传输。方法:通过对DICOM-RT四个放疗对象的解析,并对其在治疗计划系统(TPS)中的应用,设计了DICOM-IMPORT和DICOM-EXPORT两个接口。在FDS团队自主研发的精确放射治疗软件系统(ARTS)中调用这两个接口,验证接口导入导出RT-Structure(勾画信息)、RT-Plan(计划信息)、RT-Image(DRR,数字重建放射影像)、RT-Dose(剂量信息)是否正确。结果:通过测试临床病例,ARTS可以成功导入导出两大商用治疗计划系统-飞利浦Pinnacle3和拓能VENUS中获取的DICOM-RT文件。结论:通过对DICOM-RT四个放疗对象的解析,设计的两个接口实现了在精确放射治疗系统计划系统中的应用,及不同TPS数据之间的兼容。Objective： To implement the storage and transmission of CT and DICOM-RT four objects-RT-Structure,RT-Plan, RT-Image ,RT-Dose in treatment planning system （TPS）. Methods： Based on the resolution of DICOM-RT four objects, and the application in TPS, this article designed DICOM-IMPORT and DICOM-EXPORT two interfaces to implement the storage and transmission of CT and DICOM-RT objects, then the two interfaces were applied in the ARTS （Advanced/Accurate Radiation Therapy System）, which designed by FDS Team independently. Finally, the ARTS verified that the two interfaces could import and export RT-Structure（Contour information）,RT-Plan（Plan information）,RT-Image（DRR,Digital ReconstructedRadiograph）, RT-Dose（Dose information）. Results： By testing a large number of clinical cases, ARTS can import and export DICOM-RT files successfully which from two commercial TPS-Philips Pirmacle3 and Topslane VENUS. Conclusions： Through the resolution of DICOM-RT four objects, the test showes that the interface achieved application in Advanced/Accurate Radiation Therapy System and the compatibility between the different TPS.
