放疗计划归档系统的设计与应用

Design and implementation of data archiving system for radiotherapy treatment plans

目的设计并实现放疗计划归档系统(plan data archiving system, PDAS),提高计划归档工作的效能,防止计划丢失。方法读取并解析计划系统(TPS)中的原始计划文件,访问记录验证(R&V)系统数据库并获取患者的治疗记录。对计划归档相关的参数进行数据处理,并以结构化数据存入本地数据库。PDAS包括两大模块:计划归档模块和计划丢失检测模块,其中前者可分为4个部分:数据整理、数据压缩、归档核对和计划恢复。分别制定相应的逻辑规则,编写程序实现各功能模块。比对人工归档的计划数据,评估PDAS临床应用效果。结果开发并实现了PDAS各功能模块。在2年7个月的临床应用中,系统运行稳定,完成了17 614个治疗计划的归档。与人工归档相比,工作效率显著提升,放疗计划年丢失率由0.4%左右降至0。结论 PDAS可有效地提高计划归档效率,确保计划数据的安全和完整。

Objective To design and implement a plan data archiving system(PDAS)for radiotherapy treatment,in order to improve the efficiency of plan archiving and avoid plan data loss.Methods The original plan file in the treatment planning system(TPS)was read and parsed,and the record and verification(R&V)system database was accessed to obtain the patient's treatment record.PDAS processed all parameters involved in the plan archiving and saved the structured data into a local database.PDAS included two major modules,the plan archiving module and the plan loss detection module.The former could be divided into four parts,data sorting,data compression,archiving check and plan recovery.For different modules,we designed corresponding logic rules and wrote programs to realize the system.Compared with the plan data of manual archiving,the clinical application effect of PDAS was evaluated.Results Each module of PDAS was developed and implemented.During 31 months of clinical application,the system was stable,and 17614 plans were archived.Compared with manual archiving,PDAS improved the archiving efficiency significantly and reduced the plan loss rate from 0.004 or so to 0.Conclusions PDAS can improve the efficiency of plan archiving and ensure the security and integrity of plan data.
