Abstract
A device and a method for the multispectral correction of radiation hardening in computer tomography with variable tube voltage is described. In particular, a water correction and a post-reconstructive hardening correction is disclosed. To perform the water correction, project image data is corrected, in that correction values are obtained from a previously determined correction table, by means of which a correction of the projection image data can be performed. By means of an image reconstruction, this produces a corrected volumetric image.
