大型医院影像分级存储架构下归档的策略及应用

摘要

Objective: Discussion on the storage status of large hospitals medical imaging, medical imaging files of hospital massive long-term preservation. Methods: Image filing system uses a hierarchical storage structure; the use of disk arrays, tape libraries as a storage medium, long-term archiving and storage management support image files; use MD5 to detect and small file packaging technology, long-term data preservation. Results: Successful implementation of the long-term preservation and archiving image files, automated management demands massive history file of medical imaging, scientific use of online storage resources and reduce business system online storage pressure. Conclusion: Image filing system hierarchical storage mode greatly improves the image storage capacity and reduced hardware costs, improve efficiency.%目的：探讨大型医院医学影像存储现状，解决医院海量医疗影像文件的长期保存问题。方法：影像文件归档系统采用分级存储结构；利用磁盘阵列、磁带库等作为存储介质，支持影像文件的归档及长期存储管理；采用MD5检测和小文件封装的技术，使数据实现长期保存。结果：成功实现了影像文件归档和长期保存，海量历史医疗影像文件的自动化管理要求，科学利用在线存储资源，减少业务系统的在线存储压力。结论：影像文件归档系统中的分级存储模式大大提高了影像的存储容量，降低了硬件成本，提高了数据存储效益。
