We describe our current work on volume visualization techniques developed with the aim to enhance interactive exploration of medical datasets. Volumetric lenses can be applied to a volume dataset to interactively focus regions of interest within these datasets. During rendering the parts of a volume dataset intersecting the lens, which is defined by a convex 3D shape, are rendered using a different visual appearance. The lenses proposed allow to apply non-photorealistic rendering techniques interactively to aid comprehension for medical diagnosis.
