摘　　要：当前的PACS缺乏一个具有容错功能且费用合理的备份和恢复方案,解决方法比较昂贵、费时,并且难于管理和使用。网格计算是从并行计算、点对点和客户端-服务器模型发展而来的新技术,通过将网格架构应用到DICOM环境中,可以实现PACS数据实时、无缝备份和恢复。The teehndogy of PACS lacks affordable fault-tolerance storage strategies for archive, backup, and disaster recovery. Existing solutions are difficult to administer, and often time consuming for effective recovery after a disaster. Grid computing emerges as an important new field, evolving from the familiar realm of parallel, peer-to-peer, and client-server models that can address the problem of fault-tolerant timely, seamless storage for backup and recovery of medical images through applying the architecture of the grid to the DICOM environment.
