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

Comparing Diffusion Approximation with Radiation Transfer Analysis for Light Transport in Tissues
TL;DR: In this article, the applicability of the diffusion approximation over the radiative transfer theory for describing ultrafast laser transport in biological tissues is numerically studied and investigated over different kinds of tissue conditions and geometries.
Journal ArticleDOI
Excitation with a focused, pulsed optical beam in scattering media: diffraction effects.
TL;DR: This work modifications the Monte Carlo-based photon-transport model to a semi-quantum-mechanical representation that combines the wave properties of light with the particle behavior of the propagating photons, and quantifies the decrease of the energy density delivered at the geometric focus as a function of the optical depth to the mean-free-path ratio.
Journal ArticleDOI
Modeling of repeating freezing of biological tissues and analysis of possible microwave monitoring of local regions of thawing
TL;DR: It is shown that the latent heat of melting may lead to a significant difference between temperatures of the cells aggregates typical of tumors and the extracellular medium.

Photoacoustics with coherent light.
Emmanuel Bossy,Sylvain Gigan +1 more
TL;DR: It is illustrated how the photoacoustic effect can be used as a powerful feedback mechanism for optical wavefront shaping in complex media, and how the coherence of light can be exploited to enhance photoac acoustic imaging, for instance in terms of spatial resolution or for designing minimally invasive endoscopic devices.

Optical property changes as a result of protein denature in albumen and yolk.
TL;DR: Using egg albumen and egg yolk as tissue phantoms, the changes in absorption and scattering coefficients and the average cosine of the scattering angle have been quantified to model the response of tissue to laser light.

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.
