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

Optofluidic phantom mimicking optical properties of porcine livers
Ruiqi Long,Travis J. King,Tony J. Akl,M. Nance Ericson,Mark Wilson,Gerard L. Coté,Michael J. McShane +6 more
TL;DR: A polydimethylsiloxane-based liver phantom was developed to mimic the optical properties of porcine liver in the 630-1000 nm wavelength range and the anatomical geometry of liver parenchyma to facilitate the development of the liver perfusion and oxygenation monitoring system.

Monitoring of tissue optical properties during thermal coagulation of ex vivo tissues
Vivek Krishna Nagarajan,Bing Yu +1 more
TL;DR: The main objective of this study is to establish a correlation between changes in tissue optical properties and the status of tissue coagulation/damage during heating of ex vivo tissues.

Estimation of the effective phase function of bulk diffusing materials with the inverse adding-doubling method
TL;DR: It was found that the use of the GK phase function resulted in the best agreement between calculated and experimental transmittance, reflectance, and scattered radiant intensity distribution for the LDPE sample.
Quantitative Laser Doppler Flowmetry
TL;DR: Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow as discussed by the authors.

Optical non-invasive technique for vessel imaging: I. Experimental results.
Ivo Fridolin,Lars-Göran Lindberg +1 more
TL;DR: Experimental results indicate that the vessel imaging facility depends upon source-detector separation, relative position and vessel depth, and does not depend essentially on the radiant power from the light source, and it is shown that a proper choice of probe parameters can improve the vessel identification ability.

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.

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.
