判断放射治疗是否成功主要是看对肿瘤及周围重要器官和结构进行准确的定位和实施精确的治疗,高精度放射治疗是放射治疗的发展目标,然而放疗过程中存在很多影响准确度的因素,本文对放疗病人在放疗科的整个流程中可能出现误差的地方一一列出,分析各项误差产生的原因以求大家在具体的工作中(模拟定位、勾画靶区、制定计划、实体验证、摆位治疗)考虑到相应的问题从而作出相应的对策,以便更好的服务于病人。
To determine the success of radiation therapy is mainly to see the tumor and the surrounding vital organs and structures for accurate positioning and implementation of accurate treatment, high-precision radiation therapy is the development of radiation therapy goals, however, there are many radiotherapy in the process of affecting the accuracy of the factors that this article Radiotherapy patients radiotherapy in the entire process may be a place where errors listed one by one, analyze the causes of the errors in order to make everybody in the specific work (simulation positioning, targeting, planning, physical verification, Bit treatment) take into account the corresponding problems in order to make appropriate countermeasures in order to better serve the patient.
