    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: 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: 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.

    摘要: In three-dimensional X-ray imaging, with C-arm systems, scan setup has to be performed manually under fluoroscopic control. According to an exemplary embodiment of the present invention, a scan planning system for planning a data acquisition process is provided, which is adapted to predict a field of view to be reconstructed and an image quality in the field of view with respect to the actual three-dimensional scan parameter set and previously acquired images or other information. The scan planning system may be accomplished by a stand control unit.
