PROJECTION OF OBJECTS IN CT X-RAY IMAGES

A method of producing test x-ray images, the method including the steps: providing (S10) first CT data (B) of an inspection object, second CT data (BM) for metal constituents of the inspection object,third CT data (TM) for metal constituents of a target object to be inserted into the first CT data (...

Summary:A method of producing test x-ray images, the method including the steps: providing (S10) first CT data (B) of an inspection object, second CT data (BM) for metal constituents of the inspection object,third CT data (TM) for metal constituents of a target object to be inserted into the first CT data (B); transforming (S20) the first, second and third CT data (B, BM, TM) from the image space (BR) into corresponding first sinogram data (SB), second sinogram data (SBM) and third sinogram data (STM) in the radon space (RR); calculating (S30, S40) artefact sinogram data (SA) in the radon space (RR),which represent metal artefacts that have been added to the first CT data (B) on account of the target object to be inserted; transforming (S50) the artefact sinogram data (SA) back from the radon space (RR) into the image space (BR) in CT artefact data (A) for the artefacts to be inserted; and inserting the CT artefact data (A) into the first CT data (B).
