Abstract

Virtual endoscopy is among the most active areas in medical data visualization, which focuses on the simulated visualizations of specific hollow organs for the purposes of training and diagnosis. In this paper, we present a virtual angioscopy technique based on vasculature geometry reconstructed using skeleton-based implicit splines (SIS). The highly accurate implicit representation of the vasculature not only makes it possible to achieve high visual quality of perspective view inside the vessel structures, but also makes the implementation of an interactive virtual angioscopy a much easier task, as the issue of collision detection of virtual camera with vascular objects can be easily solved when the vasculature is represented in implicit form. Some experiments have been carried out to demonstrate the strengths of our technique.
