Abstract

The present invention relates to an imaging system for imaging a field of interest, in particular to a computed tomography system. The imaging system comprises an irradiation unit (2) which moves relative to a field of interest along a first trajectory (501) and along a second trajectory (503). While the irradiation unit (2) moves along the first trajectory (501), first detection data are acquired and, while the irradiation unit (2) moves along the second trajectory (503), second detection data are acquired. An intermediate image of the field of interest is reconstructed from at least the second detection data, and virtual detection data are determined by forward projection through the intermediate image. Finally, an image of the field of interest is reconstructed from the first detection data and the virtual detection data.
