  abstract =   "Reliable and complete blood-vessel segmentation is still a
               challenging problem. This is especially true in the presence
               of morphologic changes resulting from atherosclerotic
               diseases. In this paper we take advantage of partially
               segmented data with approximately identified vessel
               centerlines to comprehensively visualize the diseased
               peripheral arterial tree. We introduce the VesselGlyph as an
               abstract notation for novel focus & context
               visualization techniques of tubular structures such as
               contrast-medium enhanced arteries in CT-Angiography (CT-A).
               The proposed techniques combine direct volume rendering
               (DVR) and curved planar reformation (CPR) within a single
               image. The VesselGlyph consists of several regions where
               different rendering methods are used. Region type, the used
               visualization method and region parameters depend on the
               distance from the vessel centerline and on viewing
               parameters as well. By selecting proper rendering techniques
               for different regions, vessels are depicted in a naturally
               looking and undistorted anatomic context. In this paper we
               furthermore present a way how to implement the proposed
               techniques in software and by means of modern 3D graphics
               accelerators.",
