Theory and method of dual-energy x-ray grating phase-contrast imaging
《Chinese Physics B》2019年第10期597-602,共6页Feng Rong Yan Gao Cui-Juan Guo Wei Xu Wei Xu 
Project supported by the National Natural Science Foundation of China(Grant No.61405144);the Natural Science Foundation of Tianjin,China(Grant No.15JCQNJC42100);the Technology Special Commissioner Project of Tianjin,China(Grant Nos.16JCTPJC47200 and 16JCTPJC48100)
The principle of dual-energy x-ray grating phase-contrast imaging(DEPCI) is clarified by using the theory of x-ray interference and Fresnel diffraction. A new method of retrieving phase from the two interferograms is ...
