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

Assessing the tissue-imaging performance of confocal microscope architectures via Monte Carlo simulations
TL;DR: This work performs Monte Carlo simulations to evaluate the optical-sectioning capability of these various confocal microscope architectures in reflectance mode and finds that the DAC-PS configuration results in superior rejection of multiply scattered background light compared to all other configurations.

Systems and methods for bioluminescent computed tomographic reconstruction
TL;DR: In this paper, an image of an object is synergistically reconstructed using two or multiple imaging modalities, based on the mapped optical properties after registration between the first image and the data from the second modality.

Theoretical foundations for noninvasive measurement of variations in the width of the subarachnoid space.
TL;DR: Details of the Monte Carlo simulation of light propagation in the tissues of human head and the results of such simulation as a function of the width of the subarachnoid space, calculated for different distances between the source and detector and for a few selected values of bone thickness are presented.

Interstitial laser photocoagulation: Evaluation of a 1320 nm Nd-YAG and an 805 nm diode laser: the significance of charring and the value of precharring the fibre tip
TL;DR: In this paper, the effects of different laser wavelengths on the extent of thermal damage produced were investigated, and the role of charring around the fibre tip during ILP was investigated. And the authors concluded that using more strongly absorbed wavelengths (805 nm and 1320 nm) and pre-charring the fiber tip gave greater thermal damage during interstitial laser photocoagulation.

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.
