ABSTRACT:
In a method for operating a computed tomography apparatus, a topogram of a region of a subject, for which a volume dataset is to be obtained by computed tomography, is obtained and the image data of the topogram are analyzed to obtain an analysis result. The analysis result can be used for mixing a marking into the topogram for defining the region for which the volume dataset is to be obtained, or the analysis result can be used to align and operate a gantry of the computed tomography apparatus for obtaining the volume dataset. Manual determination and entry of the marking and/or manual control of the gantry, are thus avoided.
