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

Scattering of exciting light by live cells in fluorescence confocal imaging: phototoxic effects and relevance for FRAP studies.
TL;DR: A technique is designed, which allows us to detect subtle cell photodamage and estimate the extent and range of phototoxic effects inflicted by interaction between scattered exciting light and fluorescent probes in the vicinity of the illuminated area.

Thermal dosage investigation for optimal temperature distribution in gold nanoparticle enhanced photothermal therapy
TL;DR: In this article, the authors studied the laser-tissue interaction involved in the process of gold nanoparticle (GNP) enhanced photothermal therapy using Monte Carlo method (MC) and Beer's law were applied to calculate the heat generation of tissue and GNPs irradiated by laser.

Near‐infrared topographic measurement system: Imaging of absorbers localized in a scattering medium
TL;DR: In this article, a multichannel reflectance measurement system that uses near-infrared measurements for topographic imaging inside biological tissue was developed. But the system was used to obtain topographic images of absorbers in the scattering medium that simulated biological tissue.

Multi-time-scale heat transfer modeling of turbid tissues exposed to short-pulsed irradiations
Kyunghan Kim,Zhixiong Guo +1 more
TL;DR: A combined hyperbolic radiation and conduction heat transfer model is developed to simulate multi-time-scale heat transfer in turbid tissues exposed to short-pulsed irradiation to find that after about 10 thermal relaxation times, thermal waves fade away and the predictions between thehyperbolic and parabolic models are consistent.

Method of sample control and calibration adjustment for use with a noninvasive analyzer
TL;DR: In this article, a simplified algorithm is used that removes the daily requirement of collecting and using a non-invasive spectrum to update a calibration model, and a guide is used to substantially reduce variation in sample probe placement in relation to a skin tissue sampling site, resulting in the ability to maintain calibration performance with the use of a reference anaiyte concentration.

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.
