Imaging apparatus for generating an image of a region of interest

An image generation device for generating an image of a region of interest from detection data, the detection data being dependent on radiation after having traversed the region of interest, the radiation for traversing the region of interest being generated by a radiation source, the radiation source and the region of interest being moved relative to each other, while the detection data are generated, wherein the image generation device comprises:

• an identification unit for identifying in the detection data high density detection data, which depend on radiation, which has traversed a high density region having a density larger than a predefined density, and for identifying in the detection data non-high density detection data, which depend on radiation, which has not traversed the high density region,
• a density weighting unit for density weighting the detection data, wherein at least a part of the high density detection data has a smaller density weight than the non-high density detection data,
• a reconstruction unit for reconstructing an image of the region of interest from the weighted detection data.
