Web-based hybrid visualization of medical images

Abstract

The purpose of this paper is to visualize a still image and video on 3dimensional medical image on the web using volume rendering board and VRML(Virtual Reality Modeling Language). Using VRML, the compressed 3dimensional 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.
