ABSTRACT:
The invention relates to a computed tomography apparatus in which the measuring data acquired in a first measuring window enter the reconstruction with a weight other than that of the measuring data that can be acquired in a second measuring window, the second measuring window being situated centrally relative to the first measuring window and being smaller than the first measuring window. Depending on the weighting of the measuring data, the resultant CT image exhibits either smaller motional artefacts or a spatially more uniform noise.
