Abstract: When generating radiology reports, image findings and/or clinical information is automatically mapped to an appropriate standardized structured report template. The report template contains placeholders for information such as case-specific images and measureable values, and the placeholders are filled in by either the radiologist or by automatic procedures such as image processing algorithms, text extraction algorithms, or the like. In this manner, the radiologist is assisted in effectively generating a reader-independent high-quality diagnostic report.

Abstract: The present invention relates to the field of digital imaging, in particular to the field of estimating geometrical properties of an anatomical object. According to the present invention, geometrical properties are automatically measured and geometrical properties which have a definition based on sub-parts of the object are derived. To do this, additional geometrical information is integrated into a surface model. Geometrical properties are included into the surface model by identifying and labelling sub-parts of the surface model and fitting geometric primitives to these sub-parts. This advantageously allows to identify these sub-parts on an unseen object surface and to automatically extract relevant geometric properties.

Abstract: The invention relates to the assistance of the navigation of a catheter (1) in a vessel (2). A sequence of cross-sectional images of the portion of the vessel that is of interest is first obtained with the help of an intravascular ultrasound (IVUS) probe (3) and stored as a roadmap of the vessel. A cross-sectional image (10) that is obtained at the current position of the IVUS probe (3) can then be sorted to the position on the roadmap that is the best fit. A model (3?) of the probe, and a model (11?) of the instrument (a stent (11), for example) coupled to the probe, can be shown on a display (6) at the corresponding position on the roadmap.

Abstract: A method, computer program and device for creating a viewing protocol for medical images is described. At least a first site of interest is identified in a medical imaging data set captured from the patient. Patient record data or computer assisted detection information can be used to identify the site of interest, which may be a potential lesion. A viewing protocol for displaying medical images to a user is planned. The viewing protocol includes a viewing path along which an image of the site of interest will be displayed. The viewing protocol also includes a trigger associated with the site of interest. When the trigger event is encountered the dynamic mode of image display is reconfigured to dynamically highlight the site of interest. The viewing protocol can then be used to control the display of images so as to provide, for example, a virtual endoscope.

Abstract: A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set.

Abstract: In a system and a method for the guidance of a catheter with an electrode in an electrophysiological procedure, sequence of images of the catheter and of a resting reference catheter is generated with an X-ray device and stored together with the associated electrographic recordings from the electrodes. A reference image may then be selected from said sequence that corresponds to a desired electrographic pattern. In a next step, the positions of the catheters are localized on the reference image. The position of the reference catheter can be identified with the position of this catheter on an actual image. Thus it is possible to determine on the actual image also a target position for the catheter that corresponds to the position of this catheter on the reference image. The target position may finally be indicated on a monitor to assist the guidance of the catheter to a desired location.

According to one realization of the method, vessel segments (41) of a parametric models are fitted to differently oriented X-ray projections (P1, Pk, PN) 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.
