Patent ID: 7142628

Claim:
A computed tomography method which includes the steps of: a) generating a conical radiation beam which traverses an examination zone or an object present therein, b) rotating the conical radiation beam relative to the examination zone or the object about an axis of rotation, c) acquiring measuring values which are dependent on the intensity in the radiation beam on the other side of the examination zone during the relative rotation, 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 measuring values representing the fan beams of rays in the fan beam planes by treating the measuring values as representing rays which extend parallel to each other and perpendicularly to the transverse plane through which the puncture points are defined to form at least one CT image.
