Paper Abstract

This paper presents ongoing research in the field of volume visualization, interactive volumetric analysis and teleradiology. To cover the complete scenario from image acquisition to computer-based diagnosis and therapy support, interactive tools for volume visualization and volumetric analysis have been integrated into a state of the art teleradiology system through a general plug-in mechanism. Visualization is demonstrated as a hybrid approach integrating precise volume visualization based on the Heidelberg Raytracing Model with fast surface rendering. With respect to volumetric analysis, tools extend the 3D-viewing. They allow to measure distances, angles, areas and volumes through 3D- pointing and user controlled segmentation processes. Various input devices can be connected to control the navigation of the viewer or objects in the scene. Moreover, a haptic interface has been investigated. The realistic perception through force feedback while navigating within the 3D- reconstruction was positively judged by the medical users as well as software developers. The work is closely related to research in the field of heart, liver and cranio-facial surgery planning. In cooperation with our medical partners the development of tools as presented proceed the integration of image analysis into the clinical routine.
