Tomographic Reconstruction using Tilted Laue Analyser Based X-ray Phase-Contrast Imaging
M. C. Chalmers, M. J. Kitchen, K. Uesugi +3
Analyser-Based Phase-Contrast imaging (ABPCI) is a phase-contrast imaging method that produces high contrast images of weakly absorbing materials. However, it is only sensitive to…
Material decomposition from a single x-ray projection via single-grid phase contrast imaging
Celebrity F. Groenendijk, Florian Schaff, Linda C. P. Croton +2
This study describes a new approach for material decomposition in x-ray imaging, utilising phase contrast to both increase sensitivity to weakly-attenuating samples and to act as a…
Material Decomposition using Spectral Propagation-based Phase Contrast X-ray Imaging
Florian Schaff, Kaye S. Morgan, James A. Pollock +3
Material decomposition in X-ray imaging uses the energy-dependence of attenuation to virtually decompose an object into specific constituent materials. X-ray phase contrast imaging…
A simple, pixel-wise response correction for ring artifact removal in both absorption and phase contrast X-ray computed tomography
Linda C. P. Croton, Gary Ruben, Kaye S. Morgan +2
We present a pixel-specific, measurement-driven correction that effectively minimizes errors in detector response that give rise to the ring artifacts commonly seen in X-ray comput…
In situ phase contrast X-ray brain CT
Linda C. P. Croton, Kaye S. Morgan, David M. Paganin +8
Phase contrast X-ray imaging (PCXI) is an emerging imaging modality that has the potential to greatly improve radiography for medical imaging and materials analysis. PCXI makes it…
