Application of the Tikhonov Unfolding Method for Reconstruction of Primary X-Ray Spectra from X-Ray Equipments
Quality Control (QC) parameters for an X-ray tube depend strongly on the accurate assessment of the primary spectrum. In previous works, a methodology to assess primary spectrum using a Compton spectrometry technique has been analyzed. This methodology consists in the use of a Monte Carlo (MC) model, by means of the MCNP5 code, to reproduce the physical phenomena involving the interaction of ph...
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 کاملThe X-ray Transform and its Application in Nano Crystallography
In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopological group E(n)- the Euclidean group - acts on ℝ2 transitively. First someproperties of the Radon transform are investigated then the relationship ...
متن کاملCalculation of x-ray spectra emerging from an x-ray tube. Part I. electron penetration characteristics in x-ray targets.
The penetration characteristics of electron beams into x-ray targets are investigated for incident electron kinetic energies in the range 50-150 keV. The frequency densities of electrons penetrating to a depth x in a target, with a fraction of initial kinetic energy, u, are calculated using Monte Carlo methods for beam energies of 50, 80, 100, 120 and 150 keV in a tungsten target. The frequency...
