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 the dynamic optical properties of water on midinfrared laser ablation
TL;DR: The results of in vitro ablation of skin confirm that the dynamic optical properties of tissue need to be considered in the understanding of laser ablation as well as the design, manufacture, use, and regulation of clinical laser systems.
Journal ArticleDOI
Diffuse optical tomography with a priori anatomical information.
TL;DR: In this paper, a hierarchical Bayesian approach is proposed to improve spatial resolution and quantitative accuracy by using a priori information provided by a secondary high-resolution anatomical imaging modality, such as magnetic resonance (MR) or x-ray.

Molecular enigma of multicolor bioluminescence of firefly luciferase
TL;DR: Light-color modulation mechanism of firefly luciferase propose that the light emitter is the excited singlet state of OL− [1(OL−)*], and light emission is modulated by the polarity of the active-site environment at the phenol/phenolate terminal of the benzothiazole fragment in oxyluciferin.

Half-time image reconstruction in thermoacoustic tomography
TL;DR: It is shown that half-time reconstruction approaches can mitigate image artifacts due to heterogeneous acoustic properties of an object and permit for the explicit control of statistically complementary information that can result in the optimal reduction of image variances.
Journal ArticleDOI
Optical properties of brain tissue
TL;DR: Large differences between the optical properties of white and gray matter were observed, whereas minor differences were found between bovine and swine samples.

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.
