Abstract
The present invention relates to an imaging apparatus for generating an image of a region of interest. The imaging apparatus comprises a radiation source (2), a detection unit (6) for generating detection data and a moving unit (1, 7, 8) for moving the radiation source (2) and the region of interest relative to each other, while the detection data are generated. The imaging apparatus further comprises an identification unit (13) for identifying in the detection data high density detection data and non-high density detection data. A density weighting unit (14) density weights 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, and a reconstruction unit (15) reconstructs an image of the region of interest from the weighted detection data.
