According to the present invention, a method for controlling a computed tomography scanner for producing projections of a measurement object is proposed, in which the projections are used to create images of the measurement object. The method has comprises specifying a set-point value (sigmaset-point) for a factor (sigma(I)) that is characteristic of a quality of the projections to be produced by the computed tomography scanner; determining an actual value of the factor (sigma(I)) that is characteristic of the quality of the particular projection produced by the computed tomography scanner between the productions of successive projections; and regulating the primary intensity (I0) of an X-ray source of the computed tomography scanner, between the productions of successive projections, such that the actual value for the characteristic factor (sigma(I)) of each of the projections produced by the computed tomography scanner is kept at the specified set-point value (sigmaset-point) . A computed tomography scanner that is suitable for performing the method is also disclosed.
