  • The Energy Dependence of the Photoelectric Attenuation Coefficient of Substances 
    Chatterjee, S; Vyas, A; Ravanfar Haghighi, R; Kumar, P (Global Center for Advanced Research in Biomedical Physics and Biomedical Engineering, 2011)
    Introduction: The photoelectric attenuation coefficient of substances is known to depend upon the energy E of the photon and the effective atomic number of substances (Zeff) as (Zeff x/Ey). No definitive values about ...
  • X-ray attenuation coefficient of mixtures: Inputs for dual-energy CT 
    Haghighi, R. R; Chatterjee, S; Vyas, A; Pratik Kumar; Thulkar, S (American Association of Physicists in Medicine, 2011-10)
    The attenuation coefficient, μ(E) of substances, at any energy (E) of the x-ray photon, is known to depend on the electron density (ρe) and the effective atomic number (Zeff) of the material. While the dependence on ρe is ...
