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: An x-ray apparatus has a flat panel x-ray detector, the operation of which is susceptible to interference by strong magnetic fields. In order to allow the x-ray system to be operated concurrently with a magnetic system, such as a magnetic tracking system or a magnetic localization system, that emits a magnetic field of sufficient field strength to interfere with the operation of the flat panel x-ray detector, a control unit is provided that operates both the flat panel x-ray detector and the magnetic system. The control unit synchronizes operation of the magnetic system with the operation of the flat panel x-ray detector so that the magnetic system emits the magnetic field only at times that do not interfere with the operation of the flat panel x-ray detector.

Abstract: For noise correction in connection with a flat-panel x-ray detector, noise signals of a dark reference area are checked for deviations exceeding a specified threshold which, if any are present, will be taken into consideration separately for calculating the correction factor derived from the noise signal. Image artifacts due, for example, to high-contrast objects such as, for instance, cardiac pacemakers or metallic implants, in the x-ray image will be avoided through this measure.

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.
