为了能够从断层放疗存储中快速且可定制地自动收集放射治疗(RT)数据。 创建了人类可读的数据映射(TagMaps),以便从断层放疗档案中生成DICOM - RT(医学数字成像和通信放射治疗标准)数据,并提供对包括投照正弦图、位置校正和自适应RT剂量等“隐藏”信息的访问。 在31.5小时内批量导出了总计25000次扫描的797个数据集。所有存档信息都得以恢复,包括通过商业软件无法获取的数据。导出的数据符合DICOM标准,并与包括RayStation、Pinnacle和ProSoma在内的主要商业工具兼容。导出过程无需操作人员干预。 用于DICOM - RT数据建模的TagMap方法所产生的软件比供应商的解决方案快很多倍,所需的操作人员输入极少,并能提供大量与供应商相同的DICOM数据。该方法适用于许多临床和研究数据处理场景,并且可以进行调整以从其他专有存储类型(如Elekta、Pinnacle或ProSoma)中恢复DICOM - RT数据。 本文提出了一种将数据从专有存储转换为DICOM - RT的新方法。它提供了对隐藏在电子档案中数据的访问,为数据迁移和供应商锁定问题提供了一种可行的解决方案,并为大规模成像和放射组学研究铺平了道路。
To enable fast and customizable automated collection of radiotherapy (RT) data from tomotherapy storage. Human-readable data maps (TagMaps) were created to generate DICOM-RT (Digital Imaging and Communications in Medicine standard for Radiation Therapy) data from tomotherapy archives, and provided access to “hidden” information comprising delivery sinograms, positional corrections and adaptive-RT doses. 797 data sets totalling 25,000 scans were batch-exported in 31.5 h. All archived information was restored, including the data not available via commercial software. The exported data were DICOM-compliant and compatible with major commercial tools including RayStation, Pinnacle and ProSoma. The export ran without operator interventions. The TagMap method for DICOM-RT data modelling produced software that was many times faster than the vendor’s solution, required minimal operator input and delivered high volumes of vendor-identical DICOM data. The approach is applicable to many clinical and research data processing scenarios and can be adapted to recover DICOM-RT data from other proprietary storage types such as Elekta, Pinnacle or ProSoma. A novel method to translate data from proprietary storage to DICOM-RT is presented. It provides access to the data hidden in electronic archives, offers a working solution to the issues of data migration and vendor lock-in and paves the way for large-scale imaging and radiomics studies.
