Abstract:
1. A method for generating image data relating to a virtually prescribable X-ray tube voltage U 3 from first and second CT image data, wherein the first and second CT image data have been obtained by way of a computer tomograph by simultaneously, or nearly simultaneously, recording an object volume, the first CT image data describe a first distribution of the linear attenuation coefficient μ the first X-ray spectrum S a) providing the first and second CT image data, b) prescribing the virtual X-ray tube voltage U c) using the first and second CT image data for two prescribable base materials A, B to determine in each case a spatial density distribution ρ d) providing an effective mass attenuation coefficient <α e) determining the image data as a third distribution of effective linear attenuation coefficients μ
