Abstract:
    A method for suppressing ghost image artifacts in x-ray images is provided. In chronological order, a plurality of x-ray images of one or more objects is generated with the interposition of at least one solid-state detector for generating a visible image by incident x-radiation. From each currently generated x-ray image, a previously ascertained correction image is electronically subtracted. The last correction image ascertained is generated by a blank image, and before its use, it is examined for the presence of residual-image effects. If a predetermined limit value of a proportion of residual-image effects (proportion of residual images) is exceeded, the last correction image is discarded at least partially, and an earlier correction image ascertained by a blank image with a lesser proportion of residual images is used at least partially for correcting the current x-ray image.
