3-Dimensional Display from Video Input Data of CT Images

CT, that is, Computer Tomography, is one of the effective tools to investigate the state of the human bodies. The reconstruction of the 3-Dimensional parts of the bodies, however, depends on the surgeon's imagination from the 2-Dimensional data of the tomography. Recently it comes to be realized that the 3-D reconstruction can be directly process ed by the specialized or large stall computers. But they are still too expensive and too exaggerated to handle at each surgery by each surgeon. This study aims at making 3-D display model with low cost usefully in medical aid, where we use only simple personal computer and its devices. But the method took us too much times. So at the present paper, we used video camera for input device in order to shorten the leadtime and save operator's trouble. And the animation display of rotating, scaling and zooming up are tried successfully.
