摘要：

To make experimental study on 3-D human body virtual endoscope using 3-D image data of a human body, the geometrical model and locating of a virtual endoscope were built. By the model, we can view a virtual human body in different directions and resolutions. Then, method of ray tracing for surface detection and tri-linear interpolation for surface rendering were applied to visualize the result of virtual endoscope. A virtual endoscope system based on PC that uses the method were given and a few virtual endoscope images of 3-D human body image data were also presented. Experiments show that virtual endoscope is one of the most hopeful methods for virtual diagnosis, virtual therapy and virtual teaching.
