    摘要： The invention relates to a diagnostics device and to a method for the operation thereof comprising an X-ray system for producing X-ray images, the system comprising an X-ray device and an image system for the X-ray device, and a system for locating objects, wherein adjusting means for changing the frequency of at least one of the two systems are provided, by way of which the two systems can be coordinated with one another such that interference within successive X-ray images is virtually static, and the image system comprises a correcting device which is constructed such that the static interference is eliminated. Diagnostics devices of this type are used in various medical procedures, for example in PCI (Percutaneous Coronary Intervention) and Cardiac EP (electrophysiology) interventions.

    摘要： An x-ray diagnostics installation has an x-ray generator, an x-ray tube and an x-ray image intensifier to which a video camera with a CCD image sensor is coupled. The video camera includes a control generator that is connected to a control output of the x-ray generator and to the CCD image sensor, and controls the latter such that the read-out clock is interrupted synchronously with the video clock on the basis of a signal supplied by the x-ray generator.

    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： An x-ray diagnostics installation has an operating voltage generator, an x-ray tube, an x-ray image intensifier, a video camera, a video amplifier having controllable gain, an integration circuit and a control circuit that acts on the operating voltage for dose rate control. The x-ray diagnostics installation is fashioned such that the control circuit is connected to the video amplifier and to the integration circuit and controls these components such that the gain of the video amplifier is raised when a limit value of the dose rate control is reached, with parameters of the integration circuit being simultaneously modified.
