The applicability of diffusion theory for the determination of tissue optical properties from
time-resolved reflectance spectroscopy is investigated. Analytical expressions from diffusion …

Four different expressions, derived from the diffusion theory or the random walk model, were
used to fit time‐resolved reflectance data for the evaluation of tissue optical properties. The …

Abstract We have used Monte Carlo simulations for a two-layered diffusive medium to
investigate the effect of a superficial layer on the measurement of absorption variations from …

Improved solutions of the diffusion equation for time-resolved and steady-state spatially

A model based upon steady‐state diffusion theory which describes the radial dependence of
diffuse reflectance of light from tissues is developed. This model incorporates a photon …

In principle, the measurement of the time-resolved diffuse reflectance, as interpreted on the
basis of the diffusion theory, allows one to determine the optical properties (absorption …

An efficient method is proposed for the evaluation of the absorption and the transport
scattering coefficients from a time-resolved reflectance or transmittance distribution. The …

Accurate numerical simulations based on rigorous radiative transfer theory are used to
assess the validity of the diffusion approximation that is frequently used in bio-optical …

The time spectrum of photons diffusely reflected from a turbid medium such as tissue
following a short incident light pulse depends on the optical absorption and scattering …
