Diffraction enhanced x-ray imaging.
Diffraction enhanced imaging is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantom. The contrast is based not only on attenuation but also the refraction and diffraction proper...
متن کاملNon-destructive diffraction enhanced imaging of seeds.
Techniques that make possible the non-destructive continuous observation of plant anatomy and developmental processes provide novel insights into these phenomena. Non-destructive imaging of seeds was demonstrated using the synchrotron-based X-ray imaging technique, diffraction enhanced imaging (DEI). The seed images obtained had good contrast and definition, allowing anatomical structures and p...
متن کاملComparison of refraction information extraction methods in diffraction enhanced imaging.
Diffraction enhanced imaging (DEI) is a powerful phase-sensitive technique that generates the improved contrast of weakly absorbing samples compared to conventional radiography. The x-ray refraction contrast of the sample is an important contrast in DEI, and it vastly exceeds the absorption contrast for weakly absorbing samples imaging, which makes it hold great promise for medical, biological ...
متن کاملDiffraction Enhanced X-ray Imaging of Biological Tissues
The purpose of this study was to explore the potential of refraction contrast X-ray imaging of biological systems. Images of a UK mammography test phantom, mouse lungs, heart, liver and legs, together with a human finger, were recorded using the SYRMEP beamline. The technique used has become to be known as ‘Diffraction Enhanced Imaging’ (DEI), which utilises a silicon crystal placed between the...
متن کاملQuantitative comparison of imaging performance of x-ray interferometric imaging and diffraction enhanced imaging.
For detailed biomedical observations using the optimum phase-contrast x-ray imaging, quantitative comparisons of imaging performances of two major imaging methods--x-ray interferometric imaging (XII) and diffraction enhanced imaging (DEI)--were performed. Density sensitivity and spatial resolution of each imaging method were evaluated using phantom tomograms obtained by each method with the sam...
