中文摘要：

目的：实现CT和DICOM．1it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可以成功导人导出两大商用治疗计划系统一飞利浦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。

英文摘要：

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.
