ABSTRACT:
A weighted method is for producing images with the aid of a spiral computed tomography unit. Further, in a CT unit, the detector and beam are tuned to one another in such a way that a drop in dose rate occurs at the edges within the detector. The form of the weighting function corresponds at least approximately to the dose rate characteristic and/or to the characteristic of the signal quality of the detector.
