Abstract

The invention relates to a method for generating a tilted tomographic X-ray map comprising:- providing a 3D image data set comprising a plurality of projection X-ray images generated by a tomosynthesis apparatus by moving an X-ray tube (2) of the tomosynthesis apparatus along a path around a rotation axis relative to the examination object and irradiating the examination object with X-ray at different projection angles within a defined projection angle range,- determining, based on the 3D image data set, synthetic mammograms corresponding to different angles within the defined projection angle range,- determining a point of interest (30) in one of the synthetic mammograms,- calculating coordinates of the point of interest in said one synthetic mammogram or the 3D dataset,- determining a tilted image plane through the examination object, the tilted image plane comprising the point of interest (30) and the rotation axis,- generating the tilted tomographic X-ray image (50) in the tilted image plane based on the provided 3D image data set,and- displaying the tilted tomographic X-ray image (50).
