Abstract: A method of regularization of x-ray phase contrast imaging (XPCi) system measurement data includes obtaining air scan data of the XPCi system prior to the presence of an object undergoing imaging, performing Fourier analysis of the air scan data, computing air coefficients from the result of the performing step, obtaining object scan data of an object undergoing imaging on the XPCi system, regularizing the object scan data, and calculating at least one of absorption image data, differential phase image data, and dark field image data by using object coefficients. A system configured to implement the method and a non-transitory computer-readable medium are disclosed.
