摘要： Diagnostic angiograms only provide the projected lumen of a coronary, which is only an indirect measure of blood flow and pressure decline. According to an exemplary embodiment of the present invention, a motion compensated determination of a flow dynamics and a pressure decline for stenosis grading is provided, in which the motion compensation is performed on the basis of a tracking of a first position of a first marker and a second position of a second marker in the projection data set. This may provide for a robust and precise flow dynamics and pressure decline determination.

摘要： 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 (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.

摘要： The present invention relates to an apparatus for determining an injection point for targeted drug delivery into a patient's body by injection of the drug into a vessel feeding a target area including a target. To provide the interventionalist with an objective and quantitative assessment of potential drug injection points instead of letting him rely on his subjective impression from the visual inspection of DSA sequences, an apparatus is proposed comprising: identification means (41) for identification of a vessel tree topology of vessels feeding said target area, flow determination means (42) for determining the percentage of drug material delivered to said target after injection into different potential injection points in said vessel tree, selection means (43) for selecting as optimal injection point the potential injection point resulting in the highest percentage of drug delivery to said target.

摘要： 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.

摘要： The invention relates to a system and a method for the guidance of a catheter (20) with an electrode (21) in an electrophysiological procedure. A sequence of images (I1, . . . Ik, . . . ) of the catheter (20) and of a resting reference catheter (30) is generated with an X-ray device (10) and stored together with the associated electrographic recordings from the electrodes (21, 31). A reference image (Ik) may then be selected from said sequence that corresponds to a desired electrographic pattern (Ek). In a next step, the positions (T, R) of the catheters (20, 30) are localized on the reference image (Ik), wherein the position (R) of the reference catheter (30) can be identified with the position of this catheter (30) on an actual image (I). Thus it is possible to determine on the actual image also a target position (T′ for the catheter (20) that corresponds to the position (T) of this catheter (20) on the reference image (Ik). Said target position (T) may finally be indicated on a monitor (60) to assist the guidance of the catheter (20) to a desired location.

摘要： 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. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in.

摘要： A system for accessing a database of a plurality of image data sets includes an acquisition unit which acquires a query for searching the database for an image data set or an image data subset comprised in an image data set. The query includes at least one medically relevant term which defines a search criteria. A determining unit determines the image data set or the image data subset included in the image data set based on the strength of semantic matches between the at least one medically relevant term and (a) corresponding medical annotation(s) describing the image data set. A retrieving unit retrieves the determined image data set or image data subset from the database.
