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

In vivo cancer targeting and imaging with semiconductor quantum dots
TL;DR: Sensitive and multicolor fluorescence imaging of cancer cells under in vivo conditions are achieved and a whole-body macro-illumination system with wavelength-resolved spectral imaging is integrated for efficient background removal and precise delineation of weak spectral signatures.
MCML-Monte Carlo modeling of light transport in multi-layered tissues
TL;DR: A Monte Carlo model of steady-state light transport in multi-layered tissues (MCML) has been coded in ANSI Standard C; therefore, the program can be used on various computers and has been in the public domain since 1992.

Light dosimetry for photodynamic therapy by whole bladder wall irradiation.
TL;DR: A spherical model of the bladder, consisting of two concentric thin‐walled plastic spheres, found that the rate of change of the fluence rate at the bladder wall is more than a factor of 2 larger when the bladder cavity is filled with a light‐scattering suspension, as compared with water.

Absorption and Scattering in Plane Parallel Turbid Media
TL;DR: In this paper, the Kubelka-Munk hyperbolic equation for reflectance and transmittance of a turbid, isotropically scattering medium has been found formally identical with the solution for reflected and transmitted fluxes of Chandrasekhar's radiative-transfer equation for highly scattering media.
