Diagnosing and mapping pulmonary emphysema on X-ray projection images [PDF]
, 2013 To assess whether grating-based X-ray dark-field imaging can increase the sensitivity of X-ray projection images in the diagnosis of pulmonary emphysema and allow for a more accurate assessment of emphysema distribution.

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.

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.

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).

X-ray Fluorescence Computed Tomography (XFCT) Imaging with a Superfine Pencil Beam X-ray Source
Photonics, 2021 X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique that can be used to sense different elements or nanoparticle (NP) agents inside deep samples or tissues. However, XFCT has not been a popular molecular imaging tool because it
