Web-based hybrid visualization of medical images

The purpose of this paper is to visualize a still image and video on 3-dimensional medical image on the web using volume rendering board and VRML(Virtual Reality Modeling Language). Using VRML, the compressed 3-dimensional still image was represented effectively on the web through polygon reduction. The real time 3-dimensional volume rendering was compressed by Window Media Video 9 codec for implementation on the web. This paper focuses on detecting the most optimized 3-dimensional medical image on different bandwidths. Performance test has been carried out by evaluating the 3-dimensional medical image using various encoding bit rates on several network conditions. The network conditions were ADSL(Asymmetric Digital Subscriber Line), VDSL(Very high-data rate Digital Subscriber Line), LAN(Local Area Network), and Wireless LAN, which are common in South Korea.
