摘要
Method for correcting an with an x-ray device (13) with a scattered radiation grids (18) recorded x-ray image (1) to effects of the antiscatter grid (18), wherein the scattered radiation grids (18) a spatially periodically repeating geometric configuration and having a without object of imaging recorded calibration image (2) is used, where the calibration image (2) and the x-ray image (1) by means of a transformation into the spatial frequency space are transformed in a spatial frequency space similarity measure between the x-ray image (1) and the calibration image (2) optimization changes of the calibration image, (2) adjustment parameters describing be determined, for the correction of the adapted calibration image (2) of the x-ray image is subtracted (1) and the x-ray image (1) by application of the inverse of the transformation is transformed back into the space domain.
