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 ...

Computed radiography X-ray exposure trends
Academic Radiology, 1995Computed radiography provides correct optical density on film, independent of the incident radiation exposure, but it can result in under- or overexposure of the imaging plate. In the current study, we evaluated the radiation exposure trends of computed radiography over a 2-year period for portable chest examinations to determine and compare the ...

Stress Sensitivity of Fractured and Vuggy Carbonate: An X‐Ray Computed Tomography Analysis
Journal of Geophysical Research: Solid Earth, 2020Fractures, vugs, and pores constitute the main pore space in carbonate reservoirs. The associated pore structure—which is of key importance in terms of hydrocarbon production and fluid flow—varies with effective stress.

Analysis of foamed concrete pore structure of railway roadbed based on X-ray computed tomography
, 2020The uneven settlement of weak roadbed will lead to road subsidence, which will reduce driving comfort and even cause traffic accidents. In the treatment of weak road base, foamed concrete has become an excellent subgrade replacement material because of ...

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.
