我们报告了一种基于光栅的 X 射线微分相衬成像的双向方法。为了检索高质量且无伪影的相位图像以进行定量分析和图像处理，特别强调正确相位检索的算法。讨论了应用示例，即使在一维相位积分完全失败的情况下，也证明了该方法的功能。 (c) 2007 年美国光学学会。
We report on a two-directional approach for grating based x-ray differential phase contrast imaging. In order to retrieve good quality and artifact-free phase images for quantitative analysis and image processing, particular emphasis is put on the algorithm for proper phase retrieval. Examples of application are discussed that demonstrate the functionality of the method even in cases where the one-dimensional phase integration fails completely. (c) 2007 Optical Society of America.
