The X-ray phantom material (PM) is a kind of substitute materials of tissues of human or other biological beings in the realms of radiology and application of atomic energy. The PM is required to exhibit nearly the same interaction results as the simulated tissue after being irradiated with X-ray or γ-ray. Since the 1960s, with the development of radiology and atomic science, PM has become a hot topic in biomedical engineering. Since the first application of PM in 1906, hundreds of PM have been developed to serve as substitutes for different kinds of tissues. However, in the formulation of PM, al- though some guiding methods have already been put forward, PM are selected mainly by experiments up to now, because those methods either are not accurate enough, or lack operability or theoretical basis. This sets an obstacle to its development.
