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

Spectrophotometers for the clinical assessment of port-wine stain skin lesions: a review
TL;DR: Scanning spectrophotometry is the most versatile of the three methods but it is noted that considerable expertise is required to interpret the acquired data and narrower-band and tristimulus devices can be considerably simpler to use.

Multi-focus optical-resolution photoacoustic microscopy with ultrasonic array detection
TL;DR: In this paper, a probe for use with an imaging system, including a scanning device configured to receive a first-light beam from a light source, a beam-divider configured to split the first light beam into a plurality of second-light beams, and a focusing device was presented.

Image-guided percutaneous ablation therapies for local recurrences of thyroid tumors
TL;DR: Mini-invasive techniques more commonly employed in selected cases are reported to ameliorate local compressive symptoms, control hormonal production, and reduce the volume of neoplastic tissue prior to traditional palliative treatment.

The Pomraning-Eddington approximation to diffusion of light in turbid materials
TL;DR: In this paper, the source-free diffusion problem of light in turbid media with generalized boundary conditions is considered. And the intensity of light is considered as a sum of collimated and diffused radiance.
Journal ArticleDOI
Transport-theory-based stochastic image reconstruction of bioluminescent sources.
TL;DR: In this article, a stochastic image reconstruction methodology is proposed for solving the highly ill-posed inverse bioluminescent source problem in light-scattering media, where the unknown source distribution is expressed in terms of a set of linearly independent source basis functions.

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.

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.
