论文摘要
最近，已经开发出具有多个相光栅的X射线干涉仪用于差异相比（DPC）成像。在这项研究中，开发了一个新的框架来预测此类干涉仪的角度灵敏度响应（最小可检测到的逆向角度）。实验分别在双相和三相光栅干涉仪上进行。测量值与预测的灵敏度值相强。使用这种新方法，可以为将来的生物医学应用进一步优化X射线干涉仪的DPC成像性能。
Recently, X-ray interferometers with more than one phase grating have been developed for differential phase contrast (DPC) imaging. In this study, a novel framework is developed to predict such interferometers' angular sensitivity responses (the minimum detectable refraction angle). Experiments are performed on the dual and triple phase grating interferometers, separately. Measurements show strong consistency with the predicted sensitivity values. Using this new approach, the DPC imaging performance of X-ray interferometers with multiple phase gratings can be further optimized for future biomedical applications.
