Abstract
The invention relates to a computed tomography apparatus whose radiation source emits a conical radiation beam and is capable of scanning the examination zone along a trajectory in the form of a helix. The detector unit that is connected to the radiation source consists of a plurality of spatially separated detector segments that are mutually offset in the axial direction and each of which is arranged in such a manner that a projection onto the helix covers at least two neighboring turns of the helix. A CT image having an improved and spatially more uniformly distributed signal-to-noise ratio can be reconstructed from the CT data acquired by means of such a detector unit.
