A Proposal of Reconstruction of the Three-Dimensional Images from Slice Images of Multi-Detector CT

Abstract

 We have developed a fast volume rendering method by superimposing polygons on which slice data of CT images are pasted. Because the thickness of the polygons is zero, when the angle between the normal line of the polygons and the direction of our sight becomes larger, it discloses the side where the texture is not pasted, making the resolution of the three dimension images less clear. We solved this problem by preparing textures in 6 directions and switching them according to the direction of our sight. As only a small amount of calculation is required in this method, we can reconstruct three dimensional displays rapidly even with a conventional PC.
