摘要： An X-ray detector of conventional design having photodiodes and scintillator material arranged thereon is able, given a suitable read-out frequency matching a low dose to which the flat-panel X-ray detector is subjected, to obtain images during each read-out operation, from which images the energy of individual X-ray quanta can be derived. An item of X-ray-spectrum information about pixels in a grid pattern can be obtained thereby.

摘要： In an operating method for a medical installation, in particular an x-ray installation. In activation state of the medical installation, a control and evaluation device determines, upon input of a control command, a useful image of a subject. For this purpose, the control and evaluation device receives raw image of the subject acquired by a detector in a first detector mode, and determines the useful image therefrom on the basis of correction data. In a waiting state of the medical installation, the control and evaluation device updates the correction data for the first detector mode repeatedly after the expiration of a basic time interval since the last driving of the detector. For this purpose, the control and evaluation device receives raw data acquired by the detector and uses it to update the correction data. The control and evaluation device updates the correction data for the first detector mode even in the activation state if, since the last updating of the correction data for the first detector mode, at least an additional time interval has elapsed that is greater than the basic time interval.

摘要： In flat-panel X-ray detectors which have a multiplicity of detector elements which are in each case associated with one pixel of an X-ray image, the individual detectors generate offset signals. These offset signals are detected by recording offset images in which there is no X-ray irradiation (dark images). The offset images are recorded after the X-ray images to be corrected in time. If for each X-ray image record, an associated offset image record is generated by using a single offset image or of two, the offset images can be recorded closely in time. Ghosting effects are then not disturbing because the offset images are only used for correcting the X-ray images which cause the ghosting.

摘要： An X-ray diagnostic installation has an X-ray tube, a voltage generator, a planar solid state X-ray image converter for generating raw images, an image system and a playback device. The image system has a device for offset correction that acquires an offset image and stores it in a correction offset memory. The correction offset memory is preceded by a microphony detector that analyzes the current offset image for disturbances due to microphony and allows storage only of a current offset image, that is free of such disturbances.
