X-ray dark-field imaging from intensity flow: A Fokker-Planck approach to grating interferometry
Samantha J. Alloo, Florian Schaff, Regine Gradl +3
Grating interferometry is a promising diagnostic technique that enables simultaneous acquisition of three complementary, synergistic X-ray images: transmission, differential phase,…

Stabilizing Laplacian Inversion in Fokker-Planck Image Retrieval using the Transport-of-Intensity Equation
Samantha J Alloo, Kaye S Morgan
X-ray attenuation, phase, and dark-field images provide complementary information. Different experimental techniques can capture these contrast mechanisms, and the corresponding im…
