Recent progress in volume rendering technique has drawn much attention and expectations to its achievements. Compared to surface rendering, however, few researches have been done on volume rendering, especially on its application to three-dimensional image analysis. In this study, we have developed a modified ray-casting technique for three-dimensional image analysis in volume rendering. This technique is based on assigning appropriate opacities to different tissue regions and on specifying areas involved for rendering. Because of difficulty in specifying regions manually, we have also introduced our own GUI (Graphical User Interface) system written in Delphi language. With this technique one can remove bone from volume-rendered images or superimpose tissues such as brain and skin. Computer simulations on clinical multi-slice X-ray CT images are performed to test the feasibility of this newly developed technique.
