Design & Implementation Of The Hybrid PACS System Based On B/S And C/S

Picture Archiving and Communication System (PACS) is one of the hot points in digital hospital construction.Present PACS system mainly bases on C/S model. It requires professional technician to setup complex client program, so is not convenient for extension and maintenance, commonly applies to local network. B/S based PACS can manage medical image information in larger scale. It can reduce requirement for client station hardware, is easier for installation, upgrade and maintenance. It is one of main development point for future PACS. This paper uses .NET as its technical platform and designs a hybrid PACS system with both B/S and C/S.In this dissertation, it was analyzed the development of PACS structure, the advantage and disadvantage of B/S and C/S model, DICOM image format and code, HTML, C# based web server technique, and web database access technology. It was designed a hybrid PACS structure with both B/S and C/S, C#.NET based DICOM browser, IIS based web server, and ASP.NET database access mode. ASP.NET data access was implemented through the combination of OLEDB and XML. Web based PACS browser was realized. Its function includes user register, image processing, file information and information indexing.This study gave design and implement in hybrid PACS based B/S, C/S model and DICOM standard.
