1. An imaging apparatus for generating an image of a region of interest, the imaging apparatus comprising: a radiation source for generating radiation for traversing the region of interest, a detection unit for generating detection data, which depend on the radiation after having traversed the region of interest, a moving unit for moving the radiation source and the region of interest relative to each other, while the detection data are generated, 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 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.
