Abstract:
A method for controlling a computed tomography scanner for producing projections of a measurement object, in which the projections are used to create images of the measurement object, comprising:specifying a set-point value (&sgr;set-point) for a factor (&sgr;(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 (&sgr;(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 a 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 (&sgr;(I)) of each of the projections produced by the computed tomography scanner is kept at about the specified set-point value (&sgr;set-point).
