    Abstract: With a method for generating an x-ray image sequence for supporting an intervention on a patient with a catheter or guide wire for instance, automatic recognition of the catheter is carried out with recorded x-ray images using a computer system. The x-ray image recording parameters are changed on the basis of the determined quality of the imaging of the object, with the x-ray device preferably being automatically activated with the changed x-ray image recording parameters, to record x-ray images. The doctor can therefore concentrate on the actual intervention and does not have to worry about operating the x-ray device.

    Abstract: The invention relates to a method for locating a medical instrument (2a, 2b) at least partly inserted into an object under examination (U), there being acquired (11, 13) images of the object under examination (U) which capture the medical instrument (2a, 2b). A method which requires as little user interaction as possible can be provided by virtue of the fact that an image is acquired under first acquisition conditions and a substantially identical image is acquired under second acquisition conditions (11, 13), and the fact that the medical instrument (2a, 2b) is located from a subtraction (14) of image data sets of first and second acquisition conditions.

    Abstract: The present invention relates to a device and a method for synchronizing an image capture device with a first image data set. The image capture device is used for recording a second image data set of a periodically moving area or object. Each first image data set contains information as to the point in time, relative to the periodically moving area or object, when recording took place. The device additionally acquires periodically recurring, current information of the area as well as information concerning the recording instant of the first image data set. From the periodically recurring information and the recording instant of the first image data set, a triggering instant is derived which controls at least one recording of the second image data set by the image capture device in such a way that the second image data set contains image data synchronized to the first image data set.

    Abstract: To determine the position and orientation of an object in a x-ray image the x-ray image is initially pre-processed. A three-dimensional template (data record) of the object based on the known constructional features of the object is created. Three parameters for the position and for the orientation respectively are modified iteratively. The three-dimensional template with the parameters for position and orientation is projected in each case onto a two-dimensional plane and the created image is compared on the basis of the generation of a degree of similarity with the pre-processed x-ray image.

    Abstract: To make interventional instruments such as catheters more easily identifiable in X-ray images, the catheters are provided with marking elements which can be recognized in the X-ray image. Examples of marking elements are sphere-shaped and ring-shaped marking elements, the ring-shaped marking elements being able to identify the catheters in the manner of a barcode and so being able to make different catheters distinguishable from one another in the X-ray image.
