| 英文摘要 | x-ray phase-contrast imaging based on grating interferometry is a technique with the potential to provide absorption, differential phase contrast, and dark-field signals simultaneously. the multi-line x-ray source used recently in grating interferometry has the advantage of high-energy x-rays for imaging of thick samples for most clinical and industrial investigations. however, it has a drawback of limited field of view (fov), because of the axial extension of the x-ray emission area. in this paper, we analyze the effects of axial extension of the multi-line x-ray source on the fov and its improvement in terms of fresnel diffraction theory. computer simulation results show that the fov limitation can be overcome by use of an alternative x-ray tube with a specially designed multi-step anode. the fov of this newly designed x-ray source can be approximately four times larger than that of the multi-line x-ray source in the same emission area. this might be beneficial for the applications of x-ray phase contrast imaging in materials science, biology, medicine, and industry. |
