The verification of radiotherapy plans is an essential step in the treatment planning process. This is especially important for highly conformal and IMRT plans which produce non-intuitive fluence maps and complex 3D dose distributions. In this work we present a DICOM (Digital Imaging and Communication in Medicine) based toolbox, developed for the evaluation and the verification of radiotherapy treatment plans. The toolbox offers the possibility of importing treatment plans generated with different calculation algorithms and/or different optimization engines and evaluating dose distributions on an independent platform. Furthermore the radiotherapy set-up can be exported to the BEAM Monte Carlo code system for dose verification. This can be done by simulating the irradiation of the patient CT dataset or the irradiation of a software-generated water phantom. We show the application of some of the functions implemented in this toolbox for the evaluation and verification of an IMRT treatment of the head and neck region.
放射治疗计划的验证是治疗计划过程中的关键步骤。这对于高度适形和调强放疗计划尤为重要，因为这些计划会产生非直观的射束流强分布和复杂的三维剂量分布。在这项工作中，我们展示了一个基于DICOM（医学数字成像和通信）的工具箱，该工具箱是为评估和验证放射治疗计划而开发的。该工具箱提供了导入由不同计算算法和/或不同优化引擎生成的治疗计划，并在独立平台上评估剂量分布的可能性。此外，放射治疗设置可以导出到BEAM蒙特卡罗代码系统进行剂量验证。这可以通过模拟患者CT数据集的照射或软件生成的水模体的照射来实现。我们展示了该工具箱中实现的一些功能在评估和验证头颈部调强放疗治疗中的应用。
