Purpose In the past decade,phase-contrast imaging (PCI) has become a hot research with an increased improvement of the image contrast with respect to conventional absorption radiography.Many system parameters can affect the image contrast in PCI,in this paper,the effects of tube parameters (focal spot size,target current,tube voltage) and imaging geometry on phase contrast were studied.
