Paper Abstract

X-ray phase differences are a thousand times greater than attenuation differences, but phase imaging has found limited clinical use due to requirements on x-ray coherence which may not be easily translated to clinical practice. Instead, this work employs a conventional source to create structured illumination with a simple wire mesh. The system simultaneously collects phase, attenuation, and scatter information. X-ray coherent scatter allows differentiation between tissue types with potentially much higher contrast than conventional radiography. Coherent-scatter images are collected with simple 1D slot-scanning and an angular shield to select signatures of interest from a relatively large region.
