In this paper, we introduce an implementation and a design for a histopathological image conference system based on WEB enviroment and using an object oriented distribution technology, i.e. Common Object Request Broker Architecture(CORBA). Being independent of platform and applicable for many different developing languages, this CORBA-based Medical Image Conference System is very powerful for system development, extension and maintenance. We designed an advanced WEB client that could open a conference by using an applet. We also used Java language for being independent of different platforms and object-oriented, it has an advantage of free usage wherever there is a WEB browser. Since applet was downloaded, all communications were done CORBA IIOP(Internet Inter-ORB protocol). Netscape Enterprise Server consists of three object modules, i.e. Conference Manager(CM), Object Manager(OM) and Image Processing(IP). The Security of applet was used and the capability of API to send images between clients. The image processing object of the server-side is implemented in C++ in order to increase processing speed. The conference participants can exchange their opinions through both chatting and whiteboard. The results of response time using an image (640X480 pixels) are that from client to to CM is 79.90 ms, from CM TO OM is 40.05 ms and OM to IP is 14.00 ms. The Network is 10MBPS on LAN environment and PCs are Pentium II(300 MHZ). By using the proposed system, it is possible to open conference for the patient's histopathological images easily by communicating between the hospitals on networks.
