Abstract

Quantitative dosimetry in clinical laser treatment requires information on propagation of light in tissue related to the optical properties of the tissue. This involves the solution of the integro-differential equation of radiative transfer, as well as experimental methods to determine the optical properties involved. These activities are summarized under the name tissue optics. This paper reviews the current status of tissue optics, distinguishing between the cases of: dominant absorption, dominant scattering, and scattering about equal to absorption. Most tissues or phantom tissues of which the optical properties are available show strongly forward scattering. The absorption and scattering data of skin layers show that in many cases scattering is more important than absorption. Under such circumstances, solutions to the transport equation under laser irradiation conditions are currently lacking.
