Abstract

The invention relates to a computer-implemented method for training a scatter correction model (60) for use in an X-ray imaging system (50), comprising: generating a set of simulated X-ray image data (11,11s) with and without scattered radiation, processing the image data (11s) with scattered radiation of the set of simulated X-ray image data (11,11s) using a domain adaptation technique to provide an adapted set of simulated X-ray image data (11s-a), wherein a target domain of the domain adaptation technique represents a set of experimental X-ray image data (10s) with scattered radiation, training the scatter correction model (60) at least with the adapted set of simulated X-ray image data (11s-a), and providing the trained scatter correction model (60) for application in the X-ray imaging system (50).
