Abstract
The present disclosure provides a method for synthesizing a projection image that represents a subject or object irradiated by X-rays from a radiation source. The method may include dividing an energy spectrum of the X-rays into one or more energy bins; determining a projection value of at least one pixel; determining a weighting coefficient corresponding to an energy bin based on a variation of the energy spectrum of the X-rays; and determining a weighted projection value of the at least one pixel based on the projection value of the at least one pixel and the weighting coefficient corresponding to the energy bin. The method may further include determining a pixel value of the at least one pixel based on the weighted projection values of the at least one pixel that correspond to all the one or more energy bins.
