Abstract
The present invention relates to an apparatus () for processing of data acquired by a dark-field and/or phase contrast X-ray imaging system, the apparatus comprising an input unit (), and a processing unit (). The input unit is configured to provide the processing unit with blank scan fringe data acquired by a dark-field and/or phase contrast X-ray imaging system comprising an interferometry arrangement and detector. The input unit is configured to provide the processing unit with sample scan fringe data acquired by the dark-field and/or phase contrast X-ray imaging system, with an object to be imaged is positioned within the dark-field and/or phase contrast X-ray imaging system. The processing unit is configured to pre-process the blank scan fringe data to determine pre- processed blank scan fringe data comprising utilization of an effective point spread function 'PSF'. The processing unit is configured to pre-process the sample scan fringe data to determine pre- processed sample scan fringe data, comprising utilization of the effective point spread function 'PSF'. The effective PSF has been determined for the dark-field and/ or phase contrast X-ray imaging system.
