[Computed X-ray densitometry].
Nihon rinsho. Japanese journal of clinical medicine, 1994Computed X-ray Densitometry (CXD) is a semi-automated method of radiographic densitometry. X-ray photographs of 2nd metacarpal bone, taken with a reference Aluminum phantom, are analyzed by a computed-densitometric machine (Bonalyzer). X-ray films are imaged by a CCD camera and displayed in a screen automatically.

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 ...

X-ray computed tomography images based phase-field modeling of mesoscopic failure in concrete
Engineering Fracture Mechanics, 2019Crack nucleation and propagation in concrete is significantly affected by mesoscopic heterogeneities, resulting in distinct failure modes and mechanical behavior. In this work, the phase-field regularized cohesive zone model (PF-CZM) is combined with the

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.

Accelerating X-ray fluorescence computed tomography
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009This paper presents new approaches to accelerating X-ray fluorescence tomography (XFCT) that are grounded in both novel image acquisition strategies that improve the quality of the data acquired and in image reconstruction strategies that reduce the amount of data acquired.

3D meso-scale modelling of foamed concrete based on X-ray Computed Tomography
Construction and Building Materials, 2018Foamed concrete has been widely used in infrastructure construction and poses new challenges to design and modelling. This paper investigates the behaviour of foamed concrete with the help of X-ray Computed Tomography (XCT), which is capable of ...
