Abstract
A system and method for single step and motionless x-ray phase contrast imaging. In one embodiment, a system for single step x-ray imaging includes a clinical x-ray source, a first coded aperture mask, a second coded aperture mask, and a photon counting spectral detector. The first coded aperture mask is disposed between the x-ray source and an object to be imaged. The photon counting spectral detector is disposed to detect x-rays passing through the object. The second coded aperture mask is disposed between the object to be imaged and the photon counting spectral detector. The system can provide, from a single acquisition step, an absorption image, a phase image, and differential phase image.
