This paper discusses some of the present knowledge of the mathematical techniques used
to describe light diffusion in turbid material such as tissues. Attention will be paid to the …

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 …

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 …

Diffusion theory is widely used to describe photon migration in turbid media because it is
simple and, in certain cases, can be accurate to within a few percent. However, it neglects …

In highly scattering media, light energy fluence rate distributions can be described by
diffusion theory. Boundary conditions, appropriate to the diffusion approximation, are …

The main idea behind this book is to present a rigorous derivation of the equations that
govern light propagation in highly scattering media, with an emphasis on their applications …

In this chapter light is principally described as particles with energy hν and velocity c. These
particles are scattered or absorbed by structures in turbid media such as biological tissues …

The accuracy of the diffusion approximation is compared with more accurate solutions for
describing light interaction with biological tissues. Generally the diffusion approximation …

We study light propagation in biological tissue using the radiative transport equation. The
Green's function is the fundamental solution to the radiative transport equation from which all …

Using optical interaction coefficients typical of mammalian soft tissues in the red and near
infrared regions of the spectrum, calculations of fluence-depth distributions, effective …
