Abstract :
In this paper, we introduce a new real-time rendering algorithm for virtual endoscopy based on GPU. The algorithm reduces the amount of data collected by the Image Memory without affecting 3-D image display accuracy. And it can be applied to compute any complex ray-generation and rendering clips in the volume rendering, making use of GPU´s power of parallel computation computing and multi-data processing. Experimental results show that for the image of CT(512×512×355), this algorithm can achieve 30 frames / sec or better rendering speed without affecting the resolution of the image.
