    Abstract: For noise correction in connection with a flat-panel x-ray detector (2), noise signals of a dark area (6) are checked for deviations exceeding a specified threshold (g) 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: 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: In a method for fast angulation changes in a C-arm x-ray system, and a foot switch for effecting such fast angulation, a pedal of the foot switch that normally has a function not related to angulation of the C-arm is either permanently, or temporarily programmed, to operate as a pedal that, when depressed, automatically moves the C-arm to a predetermined angulation. The pedal can be movable between two positions, in order to selectively, automatically move the C-arm to either of two predetermined angulation positions, or can be used in conjunction with another pedal for that purpose. The pedal can also be temporarily given a security function and/or a radiation triggering function.

    Abstract: The invention relates to a method for operating a diagnostic apparatus with an x-ray system for generating x-ray images, which has an x-ray device and an image system for the x-ray device, with a system for determining the position of objects, for example a measurement catheter, and a control facility for at least the x-ray system, whereby after an x-ray pulse a first read-out containing useful information is saved as an x-ray image, immediately afterwards a second read-out not containing useful information is saved as an interference image, and the x-ray image is corrected for the purpose of minimizing interference. Such diagnostic apparatuses are used in various medical procedures, for example in PCI (Percutaneous coronary intervention) and cardiac EP (electrophysiology) interventions.

    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: To enable a rapid and safe automatic recognition of the position of the catheter, particularly for an electrophysiological examination with an automatic control system of an electrode catheter, a two-stage image evaluation of an x-ray fluoroscopy image is provided. In the first analysis step, frequency polygons are herewith developed as potential locations of the catheter with the aid of structures contained in the image. In the second analysis step, only the previously identified potential catheter positions are investigated with the aid of a template method and the actual catheter position is identified.
