Numerical Analysis of the Relationship between the Photoelectric Effect and Energy of the X-Ray Photons in CT

Purpose: Attenuation of x-rays in any object is a combined effect of scattering and absorption of x-ray photons by the atoms in the material. While the scattering part dependents linearly upon the material’s electron density (ρe) and is weakly dependent on the energy (E) of the photon, the photoele...
