Abstract
For correcting differential phase image data, differential phase image dataacquired with radiation at different energy levels is received, wherein the differential phase image datacomprises pixels, each pixelhaving a phase gradient valuefor each energy level. After that an energy dependent behavior of phase gradient valuesof a pixelis determined and a corrected phase gradient valuefor the pixelis determined from the phase gradient valuesof the pixeland a model for the energy dependence of the phase gradient values
