Towards Segmentation of the Upper Abdomen using a Multi-Object Active Shape Model

The upper abdomen presents a wide spectrum of different medical diagnoses. Surgery is a frequently used treatment ap-proach that requires an appropriate pre-surgical planning. At this, an automatic segmentation scheme is obligatory and can be solved using Active Shape Models (ASMs). Whilst the segmentation of individual organs (e.g. liver) is a well-studied problem, our approach is a more holistic one that aims at exploiting inter-organ relationships to segment a com-plex of organs.
