Abstract
A method and a device for dose modulated X-ray scanning, where, according to an example of the method, a theoretical X-ray scanning dose for a scanning region may be calculated according to a target image quality standard set for the scanning region and a reference data level determined for the scanning region. Then, an X-ray attenuation difference between each data level corresponding to the scanning region and the reference data level may be calculated according to the theoretical X-ray scanning dose. In this way, a data level where the X-ray attenuation difference with the reference data level is higher than a threshold may be selected out from the data levels corresponding to the scanning region as a target to be de-noised, and a noise reduction may be performed for the target to be de-noised.
