The meaning of DUAL-ENERGY X-RAY ABSORPTIOMETRY is absorptiometry in which the density or mass of a material (such as bone) is measured by comparing the material's absorption of X-rays of two different energies and which is used especially for determinin
摘要: PURPOSE: To obtain a subtraction image with high space resolution by interposing a filter made of an X-ray low energy component absorbing material between two sheets of phosphor intensifying screen disposed between two sheets of X-ray photographic films....
The effect of 5 fracture fixation methods on bone mineral density (BMD) measurement of femurs, using dual-energy X-ray absorptiometry (DXA) was determined in a canine model. Six regions of interest were measured, including the entire femur, the diaphysis of the femur, and small regions center...

(FMI), and body fat distribution indices in Chinese adults using dual-energy X-ray absorptiometry (DXA), and to compare those indices with those of other ethnicities using the US NHANES data.MethodsWhole-body and regional lean mass and fat mass (FM) were measured using DXA in 5688 healthy ...
The sharp and well-marked features of the HERFD–X-ray absorption near-edge structure spectra obtained enable us to determine unambiguously and with greater precision the speciation of the probed elements. This is a major technological advance, with strong benefits for the study of highly diluted ...

XPS是用已知固定波长(即固定能量)的X射线(X-ray)轰击样品,把样品中原子里的电子撞出来,然后测量撞出电子的动能以及拥有某一动能值的电子数。这样我们可以得到一个能谱图。通过测量入射X-ray与图中峰值对应的动能之差,我们可以确定样品原子中电子的结合能(bindingenergy)。然后可以查一查这个结合能与哪种元素电子的...
