摘要： 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.
摘要翻译：对于与平板X射线检测器（2）相关的噪声校正，检查暗区域（6）的噪声信号超过规定阈值（g）的偏差，如果有的话，将考虑到分别用于计算从噪声信号导出的校正因子。通过这种措施可以避免由x射线图像造成的像例如心脏起搏器或金属植入物等高对比度物体的图像伪影。

摘要： 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.
摘要翻译：通过使用例如用导管或引导线产生用于支持对患者的介入的X射线图像序列的方法，使用计算机系统用记录的X射线图像进行导管的自动识别。基于所确定的物体的成像质量来改变X射线图像记录参数，其中X射线装置优选地通过改变的X射线图像记录参数被自动激活，以记录x射线图像。因此，医生可以专注于实际的干预，而不必担心操作x射线装置。

摘要： 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.

摘要： 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.

摘要： 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.
