For the requirements of high-flux, collimation, quasi-monochromatic X-ray emissions, as well as the exploration of X-ray frequency modulation, we propose an X-ray frequency modulation method for generating different energy X-rays by controlling the electron beam deflection based on an external ...
An x-ray imaging modality called Spatial Frequency Heterodyne Imaging (SFHI) is applied in the soft x-ray water window. SFHI permits the computational deco... Brůža,P.,Pánek,... - 《Applied Physics Letters》 被引量: 2发表: 2014年 X-ray Scatter Imaging of Hepatocellular Carcinoma ...

New image enhancement technique for bone-fracture X-ray image An efficient enhancement technique for bone fracture X-ray image is presented. In this technique a phase only synthesis is used, which is well known as a detector of an image's edge lines. The edge line image derived from the ph...
The target device achieves an ultrafast response of 19.7/18.3 ns in the frequency-selective photoresponse range 0.8–9.7 MHz. This anti-interference photodetector can accurately transmit character and video data under strong light interference with a source intensity of up to 454 mW cm...

Input X- ray photons which are modulated by passing through a body to be analyzed raise the pre-excited excimer gas molecules to a lasing energy level and the coherent radiation produced is measured and produces an amplified image of the input X-ray photon modulation....
We find that the frequency of the QPO is better correlated with the soft X-ray (< 7 keV) flux than with the hard flux (> 7 keV). If soft X-rays represent the behavior of an accretion disk, the relation shows that the disk may set the LFQPO frequency. In two cases, the ...
Braugher was best known for performances in NBC’s “Homicide: Life on the Street,” for which he won an Emmy, and Fox’s sitcom “Brooklyn Nine-Nine,” for which he was Emmy nominated. He also earned critical acclaim for starring opposite Ray Romano on TNT’s dramedy “Men of a ...
