Calibration of X-ray Imaging Devices for Accurate Intensity Measurement
Historically, X-ray imaging has been used to determine geometric and qualitative intensity information, such as tooth damage or star luminosity. For many endeavors, including astronomy, non-destructive testing, medicine, and plasma physics, the ability to measure accurately the X-ray intensity in a specific energy interval has become more important. But the metrology for these measurements, nam...
متن کاملMeasurement of x-ray pulse widths by intensity interferometry.
The pulse width of hard undulator radiation (32 ps width, energy 14 keV) was determined by intensity interferometry. The method, in combination with various x-ray monochromators, enables measurements to be taken over a wide range of time frames, from ns to fs. The applicable target includes measurements of ultrafast x-ray pulse widths from fourth generation synchrotron light sources.
متن کاملSex determination by the length ratio of metacarpals and phalanges: X-ray study on Iranian population
Background: In forensic anthropological identification, we usually use body remains. Accurate sex estimation from these remains is very important and needs the knowledge of specific population standards of that area. Sometimes, human remains are damaged by environmental circumstances. So, we must examine single bones for sex estimation. One of the relatively resistant bones to environmental con...
متن کاملMeasurement of L X-ray cross-sections and relative intensities of heavy elements by 15.2 keV photons
Total L X-ray fluorescence cross-sections have been measured for the elements La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Tm, Yb and Lu using a photon energy of 15.2 keV. The measurements have been performed using an annular source of Am. The obtained cross-sections were then compared with the theoretical values evaluated using semi-empirically fitted values of L-subshell fluorescence yields and Coster...
