Low-exposure, high-quality multimodal speckle X-ray imaging via an intrinsic gradient-flow approach

Jayvan Liu, Samantha J. Alloo, Max Langer +1

We present a new approach for retrieving dark-field, phase shift, and attenuation images from speckle-based X-ray imaging data. Speckle-based X-ray imaging (SBXI) exploits sample-i…
