Abstract
This paper proposed a real-time rendering algorithm of scene in virtual endoscopy based on GPU which will meet the real-time rendering of high resolution and mass data in the imaging guided surgery (IGS). According to the characteristics of the virtual endoscopy rendering data that the lumen data is only a very small proportion (around 5%) of the total,the first thing to do is to finish the automatic segmentation of image and to get the segmentation data of lumen tissue. Then the divided data is loaded into the image memory once and make the rendering by ray casting algorithm. In addition,the multi-GPU loading is optimized. Finally,the real-time rendering of mass data is realized through the full use of rendering and parallel computing with GPU,such as 1 024×1 024×1 024.关键词
