摘要：

Various modifications of the diffusion model designed to describe photon migration in scattering and absorbing media are analyzed and compared in the nondiffusion region. A more accurate modified diffusion equation that has a broader region of applicability is introduced. The radiative-transfer equation is solved numerically to assess the validity range of different models tested and to select the best one. (C) 1997 Optical Society of America.
