title: Virtual angioscopy using spiral CT and real-time interactive volume-rendering techniques.
abstract: Our purpose was to describe a technique for visualizing the inner contours of the vasculature using contrast enhanced spiral CT and volume rendering techniques. Because the technique is similar to using a camera to look inside vessels, we call this technique "virtual angioscopy." Preliminary results suggest virtual angioscopy using volumetric 3D rendering techniques as a potentially useful technique for the noninvasive evaluation of vascular pathology.
