To enhance the reliability and portability of picture archiving and communication system(PACS), a solution of PACS based on .NET framework is proposed.Hot standby two-node cluster is applied to build database server, and the image server is separated from the database server, and onstore-nearstore-offstore hierarchical store management is applied to store image data, and two backup devices is used in this solution.After the design of architecture, the design of workflow, the design of database and the design of modules are presented, the implementation of portability on different DBMS is discussed by data model, data access layer and class factory method.The result shows that the reliability and portability of PACS is enhanced.
