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.

摘要： A method and a system for determining a physical property of an object, e.g., a diameter value of an anatomical structure, employs local object context information for determining a local physical property of the object. The context information may be a known or determined cross-sectional shape of the object. In one embodiment, a processor may be configured to provide volumetric image information of the object having a three-dimensional structure; determine the physical property of the object along its three-dimensional structure; determine the object context information of the object; and visualize the object context information and the physical property on a display.

摘要： The invention relates to an image registration apparatus for registering a first image and a second image with respect to each other. A model, which has a fixed topology, is adapted to the first image for generating a first adapted model and to the second image for generating a second adapted model, and corresponding image elements (40, 48, 49; 50, 58, 9) are determined in the first image and in the second image based on spatial positions of first image elements in the first image with respect to the first adapted model and spatial positions of second image elements in the second image with respect to the second adapted model. Since the model has a fixed topology, corresponding image elements can relatively reliably be found based on the adapted models, even if the first and second images show objects having complex properties like a heart, thereby improving the registration quality.

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 method and an image processing system (20) for the evaluation of projection images (25) generated by an X-ray imaging system (10), wherein the images (25) may show different instruments (51, 52) of a given set of interventional instruments like catheters or guide wires. The instruments are equipped with markers such that their configuration is characteristic of the corresponding instrument (51, 52). Preferably three markers are arranged on a straight line, the ratio of the distances between them being characteristic for the corresponding instrument. The image processing system (20) may then identify the instruments (51, 52) present in a given projection (25) and provide functionalities for a user that correspond to said instruments. Moreover, the system may be used to locate an instrument (51, 52) of interest in a projection image (25) if the marker configuration of that instrument (51, 52) is known a priori.
