Current sulcal modeling techniques depend, more or less, on manual interpretation. We propose a robust voxel-coding methodology for automatic extraction and parameterization of the sulcal surfaces from volume data sets. The cortical sulci are generated in two steps: initial contour extraction and final contour generation. A voxel-coding technique based on the exterior boundary of the cerebral cortex extracts the initial contours. A similar voxel-coding technique generates the final contours. Results, and comparisons with manually derived surface models, demonstrate the potential of our methodology.
