摘要：
A method and apparatus for correcting a signal representation of a radiation image of an object wherein correction by means of correction values is performed simultaneously with image read out.
Said signal representation is for example read out from a photostimulable phosphor screen, whereby correction values are obtained by flat field exposure, and whereby the correction values can be used in a low-pass filtered and/or in an undersampled manner.
