Implication

Theoretical review reveals mathematical frameworks for modeling light diffusion in turbid biological tissues, highlighting the scope and limitations of transport theory and diffusion approximations.

Key Points

To review and evaluate the mathematical techniques, capabilities, and limitations associated with modeling light diffusion and scattering in turbid materials such as biological tissue.
Reviewed optical transport theory fundamentals, including radiance, radiant energy fluence rate, boundary conditions, and phase functions.
Analyzed analytical approaches including first-order solutions, multiple scattering regimes, and diffusion approximations under various excitation geometries such as plane, spherical, beam, and pulse waves.
Examined the impact of rough interface surface scattering on light propagation.
Established the operational boundaries and constraints under which the diffusion approximation accurately models multiple scattering in dense media.
Characterized how specific source geometries (plane, spherical, beam, and pulse waves) influence mathematical tractability and spatial light distribution.
Identified interface roughness as a critical factor that alters boundary conditions and light penetration profiles in tissue.
