摘要
A method for processing image data of an X-ray device (10) comprises the steps of: receiving a plurality of two-dimensional projection images (32) from an object of interest (22), wherein the projection images have been acquired by transmitting X-rays (20) through the object of interest (20) with respect to different view angles; generating a three- dimensional raw image volume (36) from the plurality of two-dimensional projection images (32) with respect to a coordinate grid (50) adapted to the geometry of the transmitted X-rays (20); and generating a deconvolved three-dimensional image (40) by applying a two- dimensional deconvolution to slices (52) of the three-dimensional raw image volume (36), which slices (32) are adapted to the coordinate grid (50).
