In the digital era of radiology, picture archiving and communication system (PACS) has a pivotal role in retrieving and storing the images. Integration of PACS with all the health care information systems e.g., health information system, radiology information system, and electronic medical record has greatly improved access to patient data at anytime and anywhere throughout the entire enterprise. In such an integrated setting, seamless operation depends critically on maintaining data integrity and continuous access for all. Any failure in hardware or software could interrupt the workflow or data and consequently, would risk serious impact to patient care. Thus, any large-scale PACS now have an indispensable requirement to include deployment of a disaster recovery plan to ensure secure sources of data. This paper presents our experience with designing and implementing a disaster recovery and business continuity plan. The selected architecture with two servers in each site (local and disaster recovery (DR) site) provides four different scenarios to continue running and maintain end user service. The implemented DR at University Hospitals Health System now permits continuous access to the PACS application and its contained images for radiologists, other clinicians, and patients alike.
在放射学的数字时代，图像存档与通信系统（PACS）在图像检索和存储方面发挥着关键作用。PACS与所有医疗保健信息系统（如健康信息系统、放射学信息系统和电子病历）的集成，极大地改善了整个企业在任何时间、任何地点对患者数据的访问。在这种集成环境中，无缝操作严重依赖于维护数据完整性以及确保所有人都能持续访问数据。硬件或软件的任何故障都可能中断工作流程或数据，从而对患者护理造成严重影响。因此，现在任何大规模的PACS都有一个不可或缺的要求，即包括部署灾难恢复计划以确保数据来源的安全。本文介绍了我们在设计和实施灾难恢复与业务连续性计划方面的经验。在每个站点（本地站点和灾难恢复（DR）站点）配备两台服务器的选定架构提供了四种不同的场景，以继续运行并维护最终用户服务。大学医院健康系统实施的灾难恢复现在允许放射科医生、其他临床医生和患者等持续访问PACS应用程序及其包含的图像。
