医学影像存储与传输系统中数据流程的研究与应用

目的利用数据流程的改进，提高医学影像存储与传输系统（PACS）性能和影像科室的工作效率。方法以2003年7月影像检查量近9500例检查数据跟踪统计结果为依据进行分析。使用增设计算机X线摄影系统（computer radiology，CR）影像中转服务器、设立故障临时服务器的方法改变系统数据流程。结果CR中转服务器主动分担每日工作量的30％，服务器可用资源保证在40％。据发布报告的时间对比统计，较改进前缩短近7min。解决了网络瓶颈且均衡系统负荷，提高了系统性能。结论通过对PACS系统数据流程调整后，充分利用系统各项资源，减少了不必要的时间浪费，进一步提高了影像科的工作效率。

An exploration of the application of dataflow in picture archiving and communication systems

Objective To enhance the function of picture archiving and communication systems (PACS) and the efficiency of medical imaging by adjusting dataflow. Methods About 9500 examinations consecutive data in July of 2003 were analysed and and followed. The dataflow was adjusted by adding digital radiology servers and temporal servers. Results The network bottleneck was resolved and the system load balanced, then the function of the system was enhanced. The secure running of the system was ensured in condition of urgency or increasing of patients and image data. Conclusion Adjustment of dataflow in PACS makes full use of all resources, reduces unnecessary time-wasting , further improves the working efficiency in our department.
