Abstract:: Abstract: 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.
