A review of the optical properties of biological tissues
TLDR
The known optical properties (absorption, scattering, total attenuation, effective attenuation and/or anisotropy coefficients) of various biological tissues at a variety of wavelengths are reviewed in this article.Abstract:
The known optical properties (absorption, scattering, total attenuation, effective attenuation, and/or anisotropy coefficients) of various biological tissues at a variety of wavelengths are reviewed. The theoretical foundations for most experimental approaches are outlined. Relations between Kubelka-Munk parameters and transport coefficients are listed. The optical properties of aorta, liver, and muscle at 633 nm are discussed in detail. An extensive bibliography is provided. >read more

Revised Kubelka-Munk theory. I. Theory and application.
Li Yang,Björn Kruse +1 more
TL;DR: A statistical analysis of light propagation in media leads to new relationships between the K-M scattering S and absorbing K coefficients and the intrinsic scattering s and absorbing a coefficients of a material that indicate that the S and K coefficients depend non-linearly on both a and s.

Mathematical model for time-resolved and frequency-domain fluorescence spectroscopy in biological tissues.
TL;DR: By assuming that the scattering properties of the tissue are the same at the excitation and emission wavelengths, a simple relation between the fluorescence and the scatter signals is derived.
Journal ArticleDOI
Three-dimensional computation of light scattering from cells
TL;DR: In this article, the scattering cross section and average cosine of the scattering angle are computed for cells as a function of volume fraction of melanin granules and mitochondria, and it is shown that small organelles play a significant role in light scattering from cells.
Review Article Implicit and Explicit Dosimetry in Photodynamic Therapy: a New Paradigm
TL;DR: The traditional dosimetric approach, measuring each dose factor independently, may be contrasted with the recent trend to use photosensitizer photobleaching as an index of the effective delivered dose, termed here ‘implicit dosimetry’.

TL;DR: A framework for fully 3D bioluminescence tomographic image acquisition and reconstruction that exploits spectral information is described and regularized tomographic reconstruction techniques that use semi-infinite slab or FEM-based diffusion approximations of photon transport through turbid media are described.

The Optics of Human Skin
R. Rox Anderson,John A. Parrish +1 more
TL;DR: An integrated review of the transfer of optical radiation into human skin is presented, aimed at developing useful models for photomedicine.
Journal ArticleDOI
New contributions to the optics of intensely light-scattering materials.
TL;DR: In this paper, the Gurevic and Judd formulas were derived from the Kubelka-Munk differential equations, and they are exact under the same conditions as in this paper, that is, when the material is perfectly dull and when the light, is perfectly diffused or if it is parallel and hits the specimen under an angle of 60° from normal.
Journal ArticleDOI
Time resolved reflectance and transmittance for the non-invasive measurement of tissue optical properties.
TL;DR: A simple model is developed, based on the diffusion approximation to radiative transfer theory, which yields analytic expressions for the pulse shape in terms of the interaction coefficients of a homogeneous slab.

The delta-Eddington approximation for radiative flux transfer
TL;DR: In this paper, the delta-Eddington approximation was used to calculate monochromatic radiative fluxes in an absorbing-scattering atmosphere, by combining a Dirac delta function and a two-term approximation, which overcomes the poor accuracy of the Eddington approximation for highly asymmetric phase functions.
