Abstract:
The invention relates to a method of determining a corresponding image of a moving object for a reference image from an image sequence which represents the motion as a sequence of states of motion. To this end, two motion signals, representing the development of the relevant motions, are examined for similarities. Using the similarity function thus obtained, that image in the image sequence can be determined which represents at least approximately the state of motion of the object which is represented in the reference image. Furthermore, the invention relates to a system which is suitable for carrying out the method as well as to a computer program and a computer program product enabling a data processing unit to carry out the method.

Abstract:
The image processing unit (5) has an input for the image signal (8) from the X-ray apparatus and an input for a signal (9) indicating the movement phase of the imaged body volume of the patient (2), a memory storing previous images for the body and the corresponding movement phases, with determination and display of the spacing between the movement phases for the actual image and the immediately preceding image of the body volume. An Independent claim for a method for correlation of an actual image of a body volume with a preceding image for a different movement phase is also included.

Abstract:
A method and an apparatus for selectively and interactively processing data sets is proposed. A first data set is gathered and a second data set is gathered. A first feature is selected interactively from the first data set. After the selection, the first feature is brought in correspondence with a second feature in the second data set during an identification step. The first feature, the second feature and combinations thereof can be visualized.
Abstract:
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.

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. 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.
