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

TL;DR: Insight is provided into how PDT-treated arteries can develop favorable EC repopulation without SMC-derived intimal hyperplasia and this report establishes PDT-induced changes in the ECM with a result of inhibition of SMCs and stimulation of EC functions.
Journal ArticleDOI
Experimental tests of different solutions to the diffusion equation for optical characterization of scattering media by time-resolved transmittance.
TL;DR: These studies confirm experimentally that time-resolved trasmittance can be employed usefully for evaluating s values of thick scattering samples when a proper theoretical description that takes into account realistic boundary conditions is used.

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.

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.
