Abstract

A method for correcting artifacts includes recording an X-ray image of an object by an X-ray detector. A primary X-ray spectrum of X-ray radiation is provided, and an off focal radiation spectrum in relation to the primary X-ray spectrum is provided. An image X-ray spectrum is determined from the X-ray image for each image pixel. One weighting factor each is determined by calculating a quotient between high-energy irradiation and overall energy irradiation for each image pixel, and a weighted image is determined from the weighting factors of the image pixels. A high-energy image is provided from high-energy components of the image X-ray spectrum, and low-energy components of the image X-ray spectrum are processed by taking into account image features and/or structures of the high-energy image. The high-energy component and the processed low-energy component are recombined for each image pixel, and a corrected X-ray image is created.
