摘  要:二维电子线放疗计划设计需要附加铅块以适应不同靶区形状,并保护周围的正常组织。但Pinnacle计划系统不能直接将挡铅适形为医生所给的射野大小,每次需要物理师手动拖动铅块形成所需要的射野。当遇到与之前相同射野参数的二维电子线计划时,物理师需要重新布野进行剂量计算,这种方式极大降低了二维电子线计划设计效率。该研究以Qt Creator为开发平台自主研发了一款二维电子线放疗计划系统。该系统能快速设计出二维电子线放疗计划,减少物理师重复劳动。In order to adapt to different target shapes and protect the surrounding normal tissues,the design of two-dimensional electron beam radiotherapy planning requires additional lead blocks.But the Pinnacle treatment planning system can not directly shape the lead block conformity to the size of the beam field given by the doctor.Every time,physicists need to manually drag the lead block to form the required beam field.When meeting a two-dimensional electron beam treatment planning with the same field parameters as before,physicists need to rearrange the field for dose calculation,which greatly reduces the design efficiency of the two-dimensional electron beam treatment planning.In this study,we independently developed a two-dimensional electron beam radiotherapy planning system based on Qt Creator.The system can quickly design a two-dimensional electron beam radiotherapy plan,which reduces the repeated work of physicists.
