X-ray diffraction computed tomography
Medical Physics, 1987Coherent scattering of x-ray photons leads to the phenomenon of x-ray diffraction, which is widely used for determining atomic structure in materials science. A technique [x-ray diffraction computed tomography (CT)] is described, analogous to conventional CT, in which the x-ray diffraction properties of a stack of two-dimensional object sections may be

Quantitative cone beam X-ray luminescence tomography/X-ray computed tomography imaging
, 2014X-ray luminescence tomography (XLT) is an imaging technology based on X-ray-excitable materials. The main purpose of this paper is to obtain quantitative luminescence concentration using the structural information of the X-ray computed tomography (XCT ...

X-ray computed tomography [PDF]
Electronics and Power, 1978 X-ray computed tomography, derived from the Greek meaning 'to write a slice or section', has been commercially available from 1972, after its invention and development by G.N. Hounsfield at the central research laboratories of EMI in 1967. Since then, its impact on the medical world has been as great as the discovery of X-rays itself, and despite the ...

Optical coherence tomography (OCT) is an emerging technique for imaging of synthetic materials. OCT is attractive because it combines high sensitivity (>90 dB), high resolution (5 µm to 20 µm), and low cost, approximately US $75 k.

Physics in Medicine and Biology, 2006
X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today.

Whilst additive manufacturing allows the production of highly complex parts, X-ray computed tomography enables the holistic characterisation and measurement of such parts, including their intricate geometries and inner features that would not be accessible otherwise.

X‐ray‐transmission computed tomography
Medical Physics, 1977The immediate goal of clinically based x‐ray‐transmission computed tomography (CT) is to provide a measurement of the x‐ray linear attenuation coefficient in cross section with the ultimate goal of impacting on patient managerment and care. To do this with the accuracy needed for clinical goals requires the careful integration of x‐ray physics ...

X-ray computed tomography (CT) is remarkably helpful in the diagnosis of diseases of the upper abdominal organs, particularly the liver, biliary tract, and pancreas. However, CT examination has not been established as reliable pathognomonic method due to the rapid development of technique and equipment.

Ptychographic X-ray computed tomography at the nanoscale
Nature, 2010X-ray tomography is an invaluable tool in biomedical imaging. It can deliver the three-dimensional internal structure of entire organisms as well as that of single cells, and even gives access to quantitative information, crucially important both for medical applications and for basic research.
