Abstract

An apparatus and a method for correcting a CT slice image for an image artifact (330) caused by the motion of a high attenuation part (140) in an object (135) of interest. The CT slice image is based on projection images (310a b). The apparatus and method uses a footprint (315 a b) of the part in each of the projection images (310a b).
