Computed tomography-osteoabsorptiometry for assessing the density distribution of subchondral bone as a measure of long-term mechanical adaptation in individual joints [PDF]

, 1989
To estimate subchondral mineralisation patterns which represent the long-term loading history of individual joints, a method has been developed employing computed tomography (CT) which permits repeated examination of living joints.

The impact of the COVID-19 pandemic on the structure of radiation diagnostics and collective doses of the population of the Russian Federation under medical irradiation in 2020

Радиационная гигиена, 2022
Computed tomography has become the main method of early diagnostics of COVID-19 during the pandemic of the novel coronavirus infection. Based on results of computed tomography of the chest it is possible to diagnose viral pneumonia associated with COVIS ...

X-ray phase-contrast computed tomography for full-breast mastectomy imaging at the Australian Synchrotron

, 2021
One of the imaging modalities offered by the Imaging and Medical Beamline (IMBL) at the Australian Synchrotron is Xray phase-contrast propagation-based computed tomography (PB-CT). The unique combination of high coherence and high brightness of radiation

MicroCT reveals domesticated rice (Oryza sativa) within pottery sherds from early Neolithic sites (4150–3265 cal BP) in Southeast Asia

Scientific Reports, 2017
Rice (Oryza sativa) was domesticated in the Yangtze Valley region at least 6000–8000 years ago, yet the timing of dispersal of domesticated rice to Southeast Asia is contentious.

Muscle x-ray attenuation is not decreased during experimental bed rest. [PDF]

, 2013
Muscle X-ray attenuation (MXA) in Hounsfield units (HU) is decreased in dystrophy, aging, and immobilization. We hypothesized a decrease also during bed rest (BR).

Applications of X-ray computed tomography in textile field

Fushe yanjiu yu fushe gongyi xuebao, 2022
Traditional optical imaging technique used as an analysis method for microstructure can only observe surface and can't achieve 3D characterization of the material interior, which greatly limits its application in textile field.

X-ray computed tomography [PDF]

, 2023
The problem of lithium dendrites must be addressed for practical lithium metal all-solid-state batteries. Herein, three-dimensional morphological changes within Li₃PS₄ electrolyte away from the anode were observed using operando X-ray computed tomography.
