A Novel X-ray Grating to Enhance Phase Contrast Imaging

The present invention relates to improving x-ray phase contrast imaging. The invention discloses a novel grating interferometer for phase contrast imaging with hard x-rays that overcomes limitations in the level of sensitivity by utilizing the advantages of far-field interferometers. The novel design and fabrication process can easily acquire absolute...

Multilayer X-Ray Transmission Grating Array for Phase-Contrast Imaging and Tomography

Classical X-ray Computed Tomography (CT) and radiography are based on X-ray absorption and cannot show soft tissue structures as well as Magnetic Resonance Imaging (MRI). Detecting the phase delay/advance of X-rays that travel through the body could enhance soft tissue contrast 10 - 100 times. Submicron-period X-ray transmission gratings for medical...
