摘要

A method for evaluating a radiation-based image recording device by means of a recorded image data set, wherein, for the correction of the scattering effects comprises the following steps are:- Determining a litter behind the basis of data set as a function of the image data,- a pixel by pixel correction of the image data set on the basis of the litter behind the basis of data set is obtained by multiplication of the image data set with the inverse a from the quotient of the litter behind the basis of data and said image data to the respective pixel dependent function, wherein as a function of a non-linear, smooth, by means of at least one coefficient certain function with positive derivatives is used, whose amount for the value zero is one, wherein the of the image receiving coefficient dependent on parameters is determined by an optimization process or was.
