%X Using 3D visualization reconstruction technique to get the three-dimensional structure of the cerebral vessels and its related organizations is helpful for the cerebral vessel disease diagnosis. Considering its special position, morphological complexity, and changing gray information, we hope to display its spatial structure accurately using a reconstruction technique. In this paper, we present a CUDA(compute unified device architecture)based ray-casting volume rendering to express the cerebral vessel model by introducing the factor of depth and thickness such as silhouette enhancement based on curvature, boundary enhancement on depth and the depth cue enhancement based on stereo display and color blending etc. With those real-time rendering methods, the three-dimensional structural information about depth, gradient, and direction of the viewing is clearly visible. The experimental results show that those methods can not only meet the need of accuracy but also improve the rendering quality.
