simulation and comparison of radiology x-ray spectra
monte carlo method is a very accurate method to optimize medical diagnostic radiology spectra and simulation of radiation transportation. using mcnp code, radiology and mammography attenuated x-rayspectraweresimulated.the ipem report number 78 was used as a reference to compare with the geant4 and mcnp simulations because of its popularity and wide availability. the results of geant4 in 40kev s...
متن کاملX-ray spectra calculation for different target-filter of mammograms using MCNP Code
ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...
متن کاملEfficiency of X-Ray Analyses
A team of researchers with members from several countries in Europe has used a type of X-ray diffraction to reveal defects in the way a superconductor develops. In their paper published in the journal Nature, the team describes the technique they used to study one type of superconductor and what they saw. Erica Carlson with Perdue University offers a News & Views piece on the work done by the t...
متن کاملSimulation of x-ray absorption near-edge spectra and x-ray fluorescence spectra of optically excited molecules.
The x-ray absorption near-edge spectra (XANES) and fluorescence spectra of molecules in the ground state and optically excited states are computed using time-dependent density functional theory and time-dependent Hartree-Fock theory. The calculated XANES spectra of optically excited methanol, benzonitrile, hydrogen sulphide, and titanium tetrachloride and the fluorescence spectra of optically e...
متن کاملImpact of Photon Spectra on the Sensitivity of Polymer Gel Dosimetry by X-Ray Computed Tomography
Introduction: The purpose of the current study was to investigate the effect of X-ray spectra on the sensitivity of a polymer gel dosimeter imaged with a conventional computed tomography (CT) scanner. Material and Methods: The whole process of CT imaging of an irradiated polymer gel was simulated by MCNPX Monte Carlo (MC) code. The imaging of polyacrylamide gel was accomplished by means of a co...
