The invention relates to an imaging apparatus for imaging an object of interest. An analytical reconstruction unit (12) analytically reconstructs an analytical image of the object from detection data, in particular, from projection data, and an iterative reconstruction unit (13) iteratively reconstructs an iterative image of the object from the detection data, wherein a combination unit (14) combines the analytical image and the iterative image for generating a combination image. An iterative image can comprises shading artifacts, which may be caused by preprocessing the detection data before performing the iterative reconstruction. An analytical image shows reduced shading artifacts, in particular, shows no shading artifacts at all. Thus, by combining the analytical image and the iterative image a combination image can be generated, in which the shading artifacts are reduced in comparison to an iterative image, thereby improving the quality of the reconstructed final image of the object of interest.
