摘　　要：目的解决医院内部多个Mini-PACS和跨医院、异构的影像系统间影像数据的集成和共享问题。方法将网格技术与医学影像网络系统有机结合,研究医学影像网格中的存储网格的关键问题。结果根据网格面向服务的思想,结合医院实际现状,提出了适合医院影像信息共享特点的2层存储网格架构。利用存储网格提供的主要服务实现海量存储的动态扩容和数据的动态分层存储。结论医学影像存储网格可以整合多个影像网络的存储系统,为存储系统的有效利用和客户端的透明访问提供支持。Objective To resolve the sharing of the images which are dispersed in multiple mini - PACS in one hospital or in the distributed PACS in the different hospitals. Methods The grid technology and the medical image network were integrated to research some key technologies on a medical image storage grid. Results Basing on the services provided by grid and considering the hospital＇ s situation, two layers architecture of storage grid that was adapted with the sharing character of the medical information were put forward. Using the services provided by the storage grid, the dynamic storage extension was realized. Conclusion The medical image storage grid can integrate multiple storage systems in the image network. It supports the effective usage of the storage system and transparent accessing for users.
