Description

Traditional X-ray imaging methods often struggle to capture detailed structures within soft tissues due to their limited contrast capabilities. In response, this study introduces Single-Mask X-ray Phase Contrast Imaging (PCI), a pioneering technique aimed at enhancing the visualization of subtle tissue differences. Our focus lies in the single-mask approach, which utilizes a periodic X-ray absorption mask to introduce contrast-enhancing effects. Central to our methodology is a novel model that elucidates the intricate interplay between X-ray attenuation, Laplacian phase, and differential phase contributions to detector pixel intensities. We present a streamlined retrieval method capable of extracting both attenuation-based and differential phase contrast information in a single acquisition, significantly expanding imaging capabilities. This breakthrough holds immense potential for revolutionizing medical diagnostics and beyond, paving the way for new frontiers in non-invasive imaging technology.
