New Metaphors for Interactive 3D Volume Segmentation

This paper describes on-going research at the Swiss Federal Institute of Technology to develop new paradigms for interactive segmentation of medical 3D volume data. In our segmentation system we are using a haptic device as a 3D mouse with force-feedback. The paper introduces the basic components of our framework and the ideas behind our multi-modal approach. On the one hand we are trying to increase the sense of immersion of the user by allowing him to interact in a natural way with the presented data, on the other hand we are using force-feedback as an additional channel to mediate information. The segmentation of linear structures in the human body serves as a case study for our system. We successfully used our approach to extract the skeleton of a radiological colon data set, which then served as the basis for a full segmentation of the object of interest.
