Abstract


The aim of the present study is in computer supported cooperative work (Computer Supported Cooperative Work, CSCW) technology based on client / server (C / S) network architecture, network communication protocols, TCP / IP network communication protocol design to achieve based on the the CSCW technology of remote video consultation system. The CSCW technology-based materials and methods remote video consultation system client runs on the Windows XP platform, server-side running on the Windows Server 2003 platform, the system uses the TCP / IP network communication protocol as the communication protocol of the system, Windows Sockets network programming interface, using the Visual Studio 2005 development environment, Visual C development language. Based on the of CSCW technology of remote video consultation system includes both server and client. System server and client are initialized, create a socket as well as bundled address; server-side listening port to wait for client connection requests a connection request signal arrival, it receives the address of the client when the client and responds to the connection ; client receive a confirmation signal, indicating that the connection is successful, you can start sending data. Transmitted from the client data types include the input data type, the type of data type, and a DICOM image file command. Input data types, including text and graphics, text for text communication between client and graphics including lines, rectangles, circles, and freedom of drawing a line. Command data type is mainly used for the command to operate on the DICOM images, such as the window width and window level adjustment, adjust the layout of smoothing, sharpening, scaling, rotation, measurement, annotation, and other operations. Input data types, and the type of command data are defined as the corresponding class, and packaged into packets of data transmitted on the network, the receiving party to the data and, by parsing the data packets to the appropriate text, graphics, and the command to restore. The results of this study on the basis of the CSCW technology, the successful development of a CSCW technology-based remote video consultation system, the client through the Internet read and operation of server-side medical imaging, living in different places remote expert consultation Online exchanges. The system is user-friendly, easy to operate, and to optimize the operation of the image processing done, can efficiently complete the medical imaging window width and window level adjustment, adjust the layout, smoothing, sharpening, scaling, rotation, measurement, annotation operation, and in the chat rooms provided by the system with the remote expert consultation on medical imaging exchange and discussion of the real-time, online image consultation to provide a great convenience for the different regions of the teleconsultation experts. While taking advantage of encryption technology and encryption processing program running on the client, so that the safe operation of the Internet environment. Conclusion CSCW technology DICOM standard TCP / IP protocol, and database technology based on the the CSCW technology of remote image diagnosis system is a practical and efficient remote video consultation system. The system uses CSCW technology network whiteboard and online chat feature provides a real-time image and text information exchange services through the Internet network for remote consultation between experts, living in the offsite remote consultation between experts meet medical the image consultation of demand.
