Abstract

Three-dimensional visualizations of cerebral vessel structures are helpful for diagnosing diseases. However, when viewing several overlapping cerebral vessels using traditional ray casting, it´s difficult to decide clear depth ordering. As a solution, distance color blending and stereoscopic depth enhancement are combined with CUDA-based pre-integrated volume rendering and its advanced transfer function for improved depth perception.
