Advances in 3D imaging technologies allow detailed understanding of the global arrangement of multiple structures/organs, but computational challenges are also raised. We discuss two biomedical problems that either require such detailed analysis of the images or benefit from it. In particular, we consider extraction of complete vascular tree structure in micro-CT volumes with near-capillary level resolution. While discussing standard approaches, we emphasise new ideas using curvature-based regularisation of the centerlines. We also consider common segmentation problems in MRI or CT volumes, where similar appearance of tissues makes it difficult to discriminate organs independently of the context. We advocate simultaneous global analysis of the data using anatomy-based partially ordered labelling.
