Abstract

The invention relates to a computer-implemented method for providing a trained set of functions for determining scatter radiation information (53) describing a scatter radiation contribution in a two-dimensional X-ray image (50) acquired with an X-ray device (75), comprising the following steps: - providing a first evaluation function (48) to be trained, which determines as output data an average distribution data set (52) from input data comprising the X-ray image (50), which describes an average scatter radiation distribution over a variation of at least one image acquisition parameter (51); - providing a second evaluation function (49) to be trained, which determines as output data transformation parameters (43) of a transformation (44) from input data comprising the at least one image acquisition parameter (51) during the acquisition of the X-ray image (50).so that the scatter radiation information (53) can be determined by applying the transformation (44) to the mean distribution data set (52),- providing a training data set for each of a first number of basic scenarios for which only the at least one image acquisition parameter (51) is variable, wherein each training data set comprises a second number of sub-data sets for different values ​​of the at least one image acquisition parameter (51), each comprising a training X-ray image as input data for the first evaluation function (48), a training set of values ​​for the at least one image acquisition parameter (51) as input data for the second evaluation function (48), and a training scatter radiation image (57) comprising the scatter radiation distribution as the respective basic truth,- separate training of the evaluation functions (48, 49) using the training data sets, and- providing the trained first and second evaluation functions (48,49).,
