document: New paradigms for interactive 3D volume segmentation We present a new virtual reality-based interaction metaphor for semi-automatic segmentation of medical 3D volume data . The mouse-based , manual initialization of deformable surfaces in 3D represents a major bottleneck in interactive segmentation . In our multi-modal system we enhance this process with additional sensory feedback . A 3D haptic device is used to extract the centreline of a tubular structure . Based on the obtained path a cylinder with varying diameter is generated , which in turn is used as the initial guess for a deformable surface
