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

A design for a stable and reproducible phantom for use in near infra-red imaging and spectroscopy
Michael J. Firbank,D T Delpy +1 more
TL;DR: In this article, the authors describe a stable, reproducible phantom which replicates the optical properties of tissue, for use in near infrared spectroscopy and imaging using a clear, unpolymerized liquid resin, which forms a polyester on addition of a catalyst.
Journal ArticleDOI
Time-gated transillumination of biological tissues and tissuelike phantoms
TL;DR: It is shown that time gating is sensitive to variations in scattering coefficients, and the applicability and limits of time-resolved transillumination to determine the internal details of biological tissues are investigated by phantom experiments.

Molecular Fluorescence Excitation–Emission Matrices Relevant to Tissue Spectroscopy¶
TL;DR: An interactive database of the excitation–emission matrices (EEM) of known and putative endogenous fluorophores and a number of exogenous fluorescent photodynamic therapy drugs has been developed and is intended to maintain and extend this database in the public domain.

Near infrared imaging with nanoparticles
TL;DR: This review discusses applications that have successfully demonstrated the utility of nanoparticles for NIR imaging, including NIR-emitting semiconductor quantum dots (QDs), resonant gold nanoshells, and dye-encapsulating nanoparticles.

Elizabeth M. C. Hillman,Jeremy C. Hebden,Martin Schweiger,Hamid Dehghani,Florian E. W. Schmidt,David T. Delpy,Simon R. Arridge +6 more
TL;DR: The results presented in this paper represent the first simultaneous tomographic reconstruction of the internal scattering and absorbing properties of a clinical subject using purely temporal data, with additional co-registered difference images showing repeatable absorption changes at two wavelengths in response to exercise.

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.
