摘要
目的:开发一个独立的系统RTViewer对不同商用治疗计划系统的放射治疗数据进行相互验证和对比分析。方法:以放射治疗的质量控制与质量保证为重点,在深入解析DICOM-RT标准的基础上,通过研究主流TPS厂商的底层数据格式,设计DICOM格式放射治疗数据导入、可视化、分析、导出接口,开发RTViewer系统,以实现对不同TPS的放射治疗数据相互验证和对比分析,从而确保放射治疗计划实施的质量。结果:经临床病例验证,RTViewer系统可准确地解析和可视化Eclipse、XIO、Monaco、Pinnacle及Raystation等主流商用TPS获取的DICOM-RT文件。结论:通过对DICOM-RT标准的深入解析,开发的RTViewer实现了对DICOM格式文件的精确解析与可视化,可对比分析不同TPS的放射治疗数据,用于远程肿瘤放射治疗质量控制,对放射治疗计划的质量保证具有重要意义。
Objective To develop an independent system, RTViewer, for the mutual verification and comparative analysis of the radiotherapy data from different commercial treatment planning systems(TPS). Methods The quality control and quality assurance of radiotherapy were the emphases in this study. Based on the in-depth analysis of DICOM-RT standard, the underlying data formats of mainstream TPS vendors were analyzed, thereby designing an interface for the import, visualization, analysis and export of the radiotherapy data in DICOM format. Finally, RTViewer system was developed to enable the mutual verification and comparative analysis of radiotherapy data from different TPS, so as to ensure the quality of radiotherapy program implementation.Results The verification with clinical cases showed that RTViewer system accurately parsed and visualized DICOM-RT files from mainstream commercial TPS, such as Eclipse, XIO, Monaco, Pinnacle and Raystation. Conclusion Through the in-depth analysis of DICOM-RT standard, the developed RTViewer realizes the accurate parsing and visualization of DICOM format files,and achieves the comparative analysis of the radiotherapy data from different TPS. The developed RTViewer can be used for the quality control of remote tumor radiotherapy, having great significance for the quality assurance of radiotherapy plan.
