Based on the Basic Research of Distributed Storage Technology and the Purchasing Situation of Medical Image Storage, This Paper Analyzes the Problems of Hadoop Technology in Constructing Regional Medical Image Storage Platform. an s-Dicom File Format Suitable for Hdfs and a Unified Storage Architecture Combining Centralized Storage (Fc San) and Distributed Storage (Hdfs Cluster) Are Designed. a Set of Sdfo(s-Dicom File Operator) Middleware is Developed to Provide Transparent Storage Access Interface for Pacs Application Components in the Upper Layer. the Pjeg2000 Compression Technology is Introduced and Combined with Large Databases to Realize Intelligent, Stable and Efficient Storage Management. It Has Effectively Solved the Current and Future Needs of Pacs in the Hospital Imaging Center for Large/Super Large Capacity Medical Image Data Storage.
