Based On Soa Is The Design And Implementation Of Medical Image Data Exchange Platform

In recent years, SOA (Service Oriented Architecture) technology is developing fast in computer software field. With the SOA foundation standards like web service and BPEL and the SOA products become mature, many new attempts of SOA appear in different industry. As the web service has some features like loosely-couple, cross-platform, standard-interface, self-description and can access based on HTTP, it is very suitable to be the interface standard for the distributed and heterogeneous data sources information exchange platform. As the BPEL standard can orchestrate the web service flexibly and also has some features like exception handling, compensation transaction etc, it is very suitable to define a variety of exchange and sharing processes for the platform. Therefore, the adoption of SOA technology and methodology can be the ideal solution to solve the problem of integration of heterogeneous health care systems which are distributed in different area.Currently, a large number of Hospitals still use the non-digital medical imaging and lack the efficient integration of these resources. In response to this situation, this thesis achieves the design and implementation of a medical images exchange platform based on the SOA architecture and technology by leveraging some technologies of the computer science, the network communication and the image processing. With this platform we try to promote the integration and sharing of medical image resources as well as the Hospital Information System and also to push the development of the computer-aided diagnosis technology.The system’s implementation includes two parts:(1) For the 3 level hierarchy of medical organization in Shanghai, we propose the way how medical images exchanged and shared in the platform. The detail approaches include the way to access medical images in different level of medical unit, the way to provide image data access service with security and access control, the way to improve the data utilization, the way to reduce health care costs of patients and the way to support the telemedicine by provide the medical image data. (2) To implement the data integration between the exchange platform and PACS systems in medical units through international standards (DICOM, HTTP/SOAP, XML etc.). In the future, we plan to cover the data generated by CT devices and electronic health records and electronic medical records from HIS.
