摘要 目的 设计并实现肿瘤患者放疗机排程优化分配系统,以提高工作效率、保证治疗服务质量。方法 通过计算机软件对放疗中不同治疗技术、体位固定设备、摆位验证装置进行适当的建模,由记录验证系统提取出各个放疗机的工作量信息,然后采用一定算法将上述两类信息与放疗机实际工作量容纳能力结合起来,分析得到最适合于患者的放疗机。结果 本系统在本科室代替了手工查表式的放疗机分配方式,已经完成了超过5000例患者的放疗机分配。采用本系统进行患者放疗机分配后的1个月,各个放疗机工作时长差别由原来的4~5 h (平均值4.22 h)缩短至1~2 h (平均值1.84h)。通过修改系统配置文件,可实现对放疗机工作量及放疗机配置设备的快速调控。结论该系统实现了患者放疗机正确、优化分配,同时也为放疗机资源配置、工作量调控等提供了有效解决方法。
Abstract：Objective To design and develop a treatment unit selecting system in aim of enhancingwork efficiency and safety, adjusting treatment unit workload,improving quality of medical care. MethodsVarious treatment techniques, immobilization devices and setup verification devices were modeled in software. Workload of treatment units were extract from the Record and Verify System. These two types of information were then combined with the unit′s workload capability to calculate the optimal radiotherapy apparatus for tumor patient. Results The system had finished selecting radiotherapy apparatusv for more than 5000 patients since its taking place of the old patient selecting methods. Maximum variation of daily treatment duration between treatment units had decreased from 4-5 hours (mean 4.22 hours) to 1-2 hours (mean 1.84 hours) since the system have been put into operation. Workload and device configuration of various units could be controlled by easily editing of the system configuration file. Conclusions The system developed not only accomplish patient selecting in an optimal and safe way, but also provide a way of easily control the treatment unit workload.
