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

Effect of Mixed Nanobubble and Microbubble Liquids on the Washing Rate of Cloth in an Alternating Flow
Akiomi Ushida,Tomiichi Hasegawa,Naoyuki Takahashi,Toshiyuki Nakajima,Shotaro Murao,Takatsune Narumi,Hiroshige Uchiyama +6 more
TL;DR: In this paper, mixed nanobubbles and microbubble water and four types of surfactants were investigated in an alternating flow system, and the nanobble water achieved a washing rate greater than that of ion-exchanged water.

TL;DR: A novel deep learning approach that learns non-linear photon scattering physics and obtains an accurate three dimensional (3D) distribution of optical anomalies and can accurately recover the location of anomalies within biomimetic phantoms and live animals without the use of an exogenous contrast agent is proposed.

Source of error in calculation of optical diffuse reflectance from turbid media using diffusion theory.
Lihong V. Wang,Steven L. Jacques +1 more
TL;DR: It is demonstrated that both diffusion theory and similarity relations provide very accurate results when the photon sources are isotropic and buried more deeply than one transport mean free path in turbid media.

A Bayesian approach to spectral quantitative photoacoustic tomography
Aki Pulkkinen,Ben T. Cox,Simon R. Arridge,Jari P. Kaipio,Jari P. Kaipio,Tanja Tarvainen,Tanja Tarvainen +6 more
TL;DR: In this paper, a Bayesian approach to the optical reconstruction problem associated with spectral quantitative photoacoustic tomography is presented, which is validated using two-dimensional test problems composed of three biologically relevant chromophores: fat, oxygenated blood and deoxygenated blood.

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.

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.
