DICOM-RT标准解决放射治疗信息系统标准化通讯模型的构建*

背景：放射治疗需要一个以患者为中心的信息系统来整合不同系统、设备间的有关患者的所有信息,实现放疗数据的无损传输。 目的：利用DICOM-RT标准解决放疗领域中数据非标准化存取的问题。 方法：设计了一种基于DICOM-RT标准的放疗信息系统的通讯模型。此模型分为客户端模块、TCP/IP接口模块、关联模块及服务类模块4个模块,实现了发送、接收功能及查询检索功能。此外,该模型还增加了对DICOM-RT对象的支持。 结果与结论：采用DICOMan软件和dcm4chePACS系统对此模型进行多次DICOM-RT数据传输测试,测试结果表明,该模型能实现放疗数据的无损传输,有效地完成放疗相关的信息交换和共享,达到了预定目标。 

Construction of communication mode of radiotherapy information system based on DICOM radiation therapy standard

BACKGROUND: Radiation therapy requires a patient-centered information system to integrate all the information between different systems and equipments, to make the lossless transmission of the radiation data. OBJECTIVE: To solve the non-normalized data access issues in the field of radiotherapy by using DICOM-radiation therapy standard. METHODS: The paper designed a communication model for a DICOM-radiation therapy-based radiation therapy information system. This model, which adds the support for DICOM-radiation therapy objects was constituted of four modules: client module, TCP/IP interface module, correlation module and service class module, they all can send, receive, query and retrieve information. In addition, the system also contained the support for DICOM-radiation therapy objects. RESULTS AND CONCLUSION: DICOM-radiation therapy data transmission between DICOMan software and dcm4chePACS system were tested on this model. The results show that this model can transmit data losslessly and exchange and share radiation-related information effectively.
