    摘要: For the comparatively simple and precise correction of an X-ray image (RB) recorded by a digital X-ray detector (3) with comparatively little calibration, at least one gain image (G0,G1,G2) is selected from a plurality of stored gain images (G) for linking to the X-ray image (R) based on at least one parameter (Pi) characterizing the recording conditions of the X-ray image (RB), whereby the gain images (G) are stored such that they differ at least in respect of one parameter (Pi) used for the selection and whereby the selection of the at least one gain image (G0,G1,G2) is made based on the distance (d) between the parameter configuration (g0,g1,g2) of the gain image (G0,G1,G2) and the parameter configuration (p) of the X-ray image (RB) in a parameter space (35) set by the parameters (Pi).

    摘要: X-ray beam detectors in one model can individually differ from one another. This can lead to differences in the amount of noise in an image recorded with the aid of the respective X-ray beam detector. In the present case, a variable is derived using an empty image, which variable reproduces the amount of noise, and this variable then determines the type and extent of a filtering process. Hence the image processing is adapted to the respective individual noise behavior of the respective X-ray beam detector. This is particularly suitable if the X-ray beam detector is a flat-panel detector (100) with a scintillator (22) and photodetector elements (12).
