Claim One:
1. A computed tomography method which includes the steps of a) generating, while using a radiation source, a conical radiation beam which traverses an examination zone or an object present therein, b) generating a circular relative motion, including a rotation about an axis of rotation, between the radiation source on the one side and the examination zone or the object on the other side, c) acquiring, while using a detector unit, measuring values which are dependent on the intensity in the radiation beam to the other side of the examination zone during the relative motion, d) rebinning the measuring values so as to form a number of groups, each group containing the measuring values of fan beams which are situated in equidistant fan beam planes which extend parallel to one another and to the axis of rotation and are composed of rays which traverse a plane which contains the axis of rotation and extends perpendicularly to the fan beam planes of this group in puncture points which are situated on equidistant connecting lines which extend perpendicularly to the axis of rotation and parallel to one another, e) reconstructing the spatial distribution of the attenuation of the x-rays from the measuring data, formed by the rebinning of the measuring values, for rays which extend perpendicularly to the planes of the groups and through the puncture points so as to form at least one CT image:
