    Abstract: The invention relates to a method and a system for the simultaneous reconstruction of the three-dimensional vessel geometry and the flow characteristics in a vessel system. According to one realization of the method, vessel segments (41) of a parametric models are fitted to differently oriented X-ray projections (P l , P k , P N ) of the vessel system that are generated during the passage of a bolus of contrast agent, wherein the fitting takes the imaged contrast agent dynamics and physiological a priori knowledge into account. In an alternative embodiment, the vessel geometry is reconstructed progressively along each vessel, wherein a new segment of a vessel is added based on the continuity of the vessel direction, vessel radius and reconstructed contrast agent dynamics.

    Abstract: The invention relates to a system (100) for segmentation of image data describing an object comprising a first and second object component, the system comprising: a selection unit (120) for selecting a first component model of a plurality of first component models for adapting to the image data in order to delineate the first object component and for selecting a second component model of a plurality of second component models for adapting to the image data in order to delineate the second object component, a connection unit (130) for connecting the first and second component model, an initialization unit (140) for initializing the first and second component model in the image data volume, and an adaptation unit (150) for adapting the first and second component model to the image data, thereby segmenting the image data. Thus, the system (100) of the invention offers a good coverage of object variability, allowing many object models constructed from component models, while each component model is optimized to describe the modeled object component. Consequently, selecting an optimal first and second component model and an optimal way of connecting them improves the flexibility, robustness, and accuracy of the image data segmentation.
