This paper solves the radiative transport equation in a slab using the diffusion approximation
in one-dimension. The absorption and scattering coefficients as well as the first moment of …

The propagation of light in tissue may be calculated by exact transport theory, or the
approximate diffusion theory, provided the optical properties are known at the source …

The diffusion approximation of the radiative transfer equation is a model used widely to
describe photon migration in highly diffusing media and is an important matter in biological …

Biological tissue scatters light mainly in the forward direction where the scattering phase
function has a narrow peak. This peak makes it difficult to solve the radiative transport …

We study light propagation in tissues using the theory of radiative transport. In particular, we
study the case in which there is both forward-peaked and large-angle scattering. Because …

This paper is the first of two reviewing the propagation of electromagnetic radiation of
wavelength 0.25–10 μ m in tissue. After a brief discussion of light/tissue interactions, a …

We study theoretically light backscattered by tissues using the radiative transport equation.
In particular we consider a two-layered medium in which a finite slab is situated on top of a …

The energy fluence rate in a slab of tissue has been calculated for a monodirectional and
unpola-rized incident light beam of infinite diameter perpendicular to the tissue surface …

The diffusion approximation to the radiative transport equation applies for light that has
propagated deeply into an optically thick medium, such as biological tissue. It does not …

The distribution of light in laser‐irradiated biological medium is computed using four different
procedures. Values computed with Beer's law of attenuation, Kubelka‐Munk theory, the …
