ABSTRACT:
A computer tomography device includes an X-ray source (1) and an X-ray detection system (3) for forming a number of density profiles of an object to be radiologically examined. A reconstruction unit (4) derives an image signal from the density profiles. A control system (20) adjusts the X-ray source (1) on the basis of a density value of the object and the control system is arranged to adjust the X-ray source on the basis of a part of the object to be examined. The control system is also arranged to adjust the X-ray source on the basis of a reference adjustment of the X-ray source. The reference adjustment is dependent on the part of the object to be examined.
