| Research Abstract |
The objective of the research is to develop an on-line 3-D visualization system by combining 3-D volume rendering technique and ultrasound imaging device, The system can be applied for medical diagnosis. While 3-D volume rendering technique has been investigated many years, direct connection of imaging devices and volume rendering engine has not been reported. The system developed in the research is one of the first one that can be used for practical medical diagnosis. Ultrasound imaging devices produce lower quality images than MRI imaging devices, but it has potentiality to produce real-time images. The system can reconstruct nearly real-time animation images by connecting imaging devices and rendering computer using high speed computer network. We also developed high speed parallel volume rendering algorithm to achieve higher rendering performance.
