Interactive segmentation of anatomical structures within digital volumes

In this communication, the authors give the first results of a geometrical modelling approach they have developed for representing anatomical structures. First, the authors describe briefly the main features of this approach which combines volumetric analysis and surface modelling. Its first step is an interactive segmentation of digital volumes: the authors introduce an original method to accurately perform this segmentation. Then, the authors present some results, in terms of implementation parameters and 3D medical imaging applications
