    During real-time medical data exploration using volume rendering, it is often difficult to enhance a particular region of interest without losing context information. In this video, we present a new illustrative technique for focusing on a user-driven region of interest while preserving context information. Our focal probes define a region of interest using a distance function which controls the opacity of the voxels within the probe, exploit silhouette enhancement and use non-photorealistic shading techniques to improve shape depiction.
