Diffraction enhanced x-ray imaging.
Diffraction enhanced imaging is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantom. The contrast is based not only on attenuation but also the refraction and diffraction proper...
متن کاملX-Ray-Based Detection Systems
The standard airport hand-baggage scanner has a fan-shaped or scanning x-ray beam that is transmitted through the object to be inspected. The absorption of x-rays is usually measured by a line of detectors, and a high-resolution image, derived from the degree of absorption of the beam, is produced. The image depends primarily on the density of objects located in the bag along the beam of the x-...
متن کاملX-ray multilayer monochromator with enhanced performance.
An x-ray multilayer monochromator with improved resolution and a low specular background is presented. The monochromator consists of a lamellar multilayer amplitude grating with appropriate parameters used at the zeroth diffraction order. The device is fabricated by means of combining deposition of thin films on a nanometer scale, UV lithography, and reactive ion etching. The performance of thi...
متن کاملDetection of breast cancer using non-invasive X-ray diffraction technique of hair: A preliminary study
Background: An early diagnosis of breast cancer relates directly to an accurate treatment plan and strategy. Early detection of breast cancer before its development would be a significant reduction of morbidity and mortality rates. The aim of this preliminary study is to investigate the sensitivity of Wide Angle X-ray diffraction (WAXRD) method on women hair samples of healthy and breast cancer...
