| 英文摘要 | x-ray grating interferometry is a method fur x-ray wave front sensing and phase contrast imaging that has been developed over past few years. contrast and resolution are the criteria used to specify the quality of an image. in characterizing the performance of this interferometer, the contrast transfer function is considered in this paper. the oscillatory nature of the contrast transfer function (ctf) is derived and quantified for this interferometer. the illumination source and digital detector are both considered as significant factors controlling image quality, and it can be noted that contrast and resolution in turn depends primarily on the projected intensity profile of the array source and the pixel size of the detector. furthermore, a test pattern phantom with a well-controlled range of spatial frequencies was designed and imaging of this phantom was simulated by a computer. contrast transfer function behavior observed in the simulated image is consistent with our theoretical of. this might be beneficial for the evaluation and optimization of a grating-based x-ray phase contrast imaging system.
