摘　　要：目的探讨PACS服务器架构模式在应急处理方案中的应用价值。方法针对我院影像设备多及数据流量大的特点,PACS服务器设计采用分级体系管理架构。信息中心设立企业级服务器2台,1台为中心服务器,1台作为后备服务器,完成所有影像及病人资料接收、存储、调度及分发等服务,影像科及临床科分别设置2台(可扩充)影像前置服务器及1台临床前置服务器(可扩充),解决大并发访问对主服务器的压力及多个服务器之间的相互热备;开发提供一套科研教学前置服务器,用于教学及科研资料的存储及调阅。结果服务器分级体系架构在PACS遇到故障或灾难时,如中心服务器单点故障、中心服务器整体系统不可用或某个前置服务器系统不可用3种情况下,均能进行相应的应急处理,确保整个PACS系统正常运行。结论采用服务器分级架构体系强调多个服务器之间的相互热备,对于保障发生灾难性故障时整个系统的安全性具有重大的意义。Objective To investigate the applied value of PACS server architecture in the emergency measures. Methods According to the characteristic of imaging equipments and the data flux in our hospital,the classification server architecture of PACS is used. Two enterprise servers are in the information center as main servers, two are in the department of radiology as front imaging server, and one is in the clinical department as clinical server. All the servers can substitute temporarily. Results The classification server architecture can take action as the emergency, such as the single center server failure, the center server system failure, or the any of the front serve failure. It can assure the whole PACS works in order. Conclusion The classification server architecture can substitute temporarily anytime. It is very important to assure the whole PACS security when the balefulness occur.
