title: Comparison of photon interaction parameters of some tissues and their substitutes.
abstract: The photon interaction parameters such as mass attenuation coefficient (μ/ρ), effective atomic number (Z eff) and effective electron density (N el) must be identical for the phantom material and their tissue. In the present study, the μ/ρ, Z eff, and N el for muscle, breast, lung tissue have been computed, and their substitutes such as Griffith muscle, Griffith breast, Griffith lung, Alderson muscle A, Alderson muscle, and Alderson lung. Also compared were μ/ρ, Z eff, and N el for muscle, breast, lung tissue, and their substitutes. It can be shown that Alderson muscle B is better substitute for muscle than Griffith muscle and Alderson muscle A. Similarly, the photon interaction parameters of tissue substitutes of lung and breast with their original tissue were also compared.
