Abstract

In this paper we present a novel system for segmentation refine-ment, which allows for interactive correction of surface models generated from imperfect automatic segmentations of arbitrary volumetric data. The proposed approach is based on a deformable surface model allowing interactive manipulation with a hybrid user interface consisting of an immersive stereoscopic display and a Tablet PC. The user interface features visualization methods and manipulation tools specifically designed for quick inspection and correction of typical defects resulting from automated segmentation of medical datasets. A number of experiments show that typical segmentation problems can be fixed within a few minutes using the system, while maintaining real-time responsiveness of the system.
