摘要：
The method(30) for simulating reduction of acquisition dosage of an X-ray system comprises providing (32) first X-ray image information comprising first noise, the first X-ray image information having been acquired with a first dosage setting providing (34) a second dosage setting determining (36) a noise difference for obtaining simulated second X-ray image information acquired with the second dosage setting and applying (38) the noise difference to the first X-ray image information for obtaining the simulated second X-ray image information comprising second noise. The noise difference is at least partly dependent on at least one of a colouring of the first noise, a noise power spectra of the first noise, a colouring of the noise difference, a power spectra of the noise difference, an intensity distribution of the first X-ray image information and a local intensity distribution of the first X-ray image information.
