    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.
