Monte-Carlo simolation of X-ray energy spectrum for single and dual-energy radiography

Single-energy radiography is one of the most everyday nondestructive/noninvasive imagine methods that generate detailed images of tumors, nodules, crackes, defects,and discountuities has inside of human body
or an object.Dual-energy X-ray is a novel technique which uses two X-ray specturam for imagining.It can produce much higher contrast for radiographs for when two different subjects with different atomic numbers
are close to each other.In this study,X-ray beam geometry has been precisely implemented in the code. Tungsten target anode material and the angel of 20 degrees is used as typical X-ray source's anode.Electron-photon transformation cross-sections have been taken from ENDF data libraries.Photon energy distribution finally calculated exactly after inherent and or/additional filters.Effects of filtering materials with different
thicknesses on HE and LE have been investigated. Excellent agreement results obtained in the spectrums generated by our Monte-Carlo simulation by IPEM software and experimental data.In this study filter quality effect has been conducted as well.The results of this investigation are very important in optimizing doze calculation, image quality consideration
and a lot of other parameters in the area of the medical and industrial imaging field.
