Abstract: An information retrieval system (IPS). The system comprises an input interface (IN) for receiving a query related to an object of interest. A concept mapper (CM) is configured to map the query to one or more associated concept entries of a hierarchic graph data structure (ONTO). The entries in said structure encode linguistic descriptors of components of a model (GM) for said object (OB). A metric-mapper (MM) is configured to map the query to one or more metric relationship descriptors. A geo-mapper (GEO) is configured to map said concept entries against the geometric model linked to the hierarchic graph data structure to obtain spatio-numerical data associated with said linguistic descriptors. A metric component (MTC) is configured to compute one or more metric or spatial relationships between said object components based on the spatio-numerical data and the one or more metric relationship descriptors.

Abstract: During a medical intervention such as an angiography, the X-ray examination equipment (such as that mounted on a C-arm) produces a very large number of imaging frames of the intervention, as it progresses. This information contains frame sequences which can be effectively used to improve a medical report of the intervention. The sequence will contain sequences which contain similar clinical information though, and these frames may be considered to be redundant and not useful for inclusion in the medical report. The aspects detailed herein enable a selection of non-redundant sequences and/or frames, based on contextual information, obtained from the sequence of images, and/or other medical equipment, during an intervention. In this way, the redundancy inherent in the original frame sequence can be removed, leaving a set of prepared candidate sequences for insertion into a multimedia or documentary medical report.

Abstract: An apparatus provides a patient specific 3D model of a body part. At least one 2D X-ray image including 2D X-ray image data of a vascular structure of a patient's body part is provided. A 3D model of the body part is provided, the 3D model including a 3D modelled vascular structure. At least one parameter commands an appearance of the 3D modelled vascular structure. The 3D modelled vascular structure is compared with the 2D X-ray image data of the vascular structure to determine the at least one parameter. The 3D model is updated as a function of the determined at least one parameter. A medical report is generated based on information determined from the 3D model.

Abstract: An apparatus for assessing a vessel of interest and a corresponding method are provided in which the modeling of the hemodynamic parameters using a fluid dynamics model can be verified by deriving feature values from the segmented vessel of interest and inputting these feature values into a classifier. The classifier may then determine, based on the feature values whether the segmentation has been performed from proximal to distal, from distal to proximal or cannot be determined from the provided data. An incorrect segmentation order can thus be identified and potentially be corrected, thereby avoiding inaccurate simulation results.
