The manner which decrease of the collection dose of the x-ray system simulation is done, the computer system and the x-ray system

摘要

This invention is something regarding all x-ray generation technology. As for x-ray image collection, it is desirable to do with the minimum necessary dose in order to obtain the image quality of desire. Therefore, simulation is done the manner which, the computer system and the x-ray system, computer reading possible media and program element are offered the decrease of the collection dose of the x-ray image. As for the manner 30 which decrease of the collection dose of the x-ray system simulation is done, the step 32 which supplies the 1st x-ray image information which possesses the 1st noise which was collected at 1st dose set value and, the step 34 which supplies 2nd dose set value and, the simulation which is collected at 2nd dose set value the step applying 36 which decides the noise difference in order to obtain the 2nd x-ray image information which is done and the said noise difference to 1st x-ray image information, the simulation which possesses 2nd noise it possesses with the step 38 which obtains the 2nd x-ray image information which is done. The above-mentioned noise difference, color tone of 1st noise, noise power spectrum of 1st noise, color tone of the above-mentioned noise difference, power spectrum of the said noise difference, depends at least on one inside intensity distribution of 1st x-ray image information and local intensity distribution of the said 1st x-ray image information at least partly.
