Diffuse optics for tissue monitoring and tomography
TLDR
The theoretical basis for near-infrared or diffuse optical spectroscopy (NIRS or DOS) is developed, and the basic elements of diffuse optical tomography (DOT) are outlined.

High Weight Fraction Surfactant Solubilization of Single-Wall Carbon Nanotubes in Water
We report a simple process to solubilize high weight fraction single-wall carbon nanotubes in water by the nonspecific physical adsorption of sodium dodecylbenzene sulfonate. The diameter…

Concurrent MRI and diffuse optical tomography of breast after indocyanine green enhancement.
TLDR
It is found that DOT provides for localization and quantification of exogenous tissue chromophore concentrations and the use of ICG, an albumin bound absorbing dye in plasma, demonstrates the potential to differentiate disease based on the quantified enhancement of suspicious lesions.

Spectroscopy and Imaging with Diffusing Light
Visually opaque media are ubiquitous in nature. While some materials are opaque because they strongly absorb visible light, others, such as loam, white paint, biological tissue and milk, are opaque…

Spatially varying dynamical properties of turbid media probed with diffusing temporal light correlation
The diffusion of correlation is used to detect, localize, and characterize dynamical and optical spatial inhomogeneities in turbid media and is accurately modeled by a correlation diffusion equation.…

In vivo cerebrovascular measurement combining diffuse near-infrared absorption and correlation spectroscopies.
TLDR
Two near-infrared diffuse optical techniques are combined to study variations of blood flow, haemoglobin concentration, and blood oxygen saturation in the functioning rat brain to demonstrate self-consistency and compare with other measurements in the literature.

Diffuse Optical Tomography of Cerebral Blood Flow, Oxygenation, and Metabolism in Rat during Focal Ischemia
TLDR
The authors report DOT images of hemodynamic and metabolic contrasts using a rat middle cerebral artery occlusion (MCAO) stroke model, and demonstrates how these hemodynamic measures can be synthesized to calculate an index of the oxygen extraction fraction (OEF) and the cerebral metabolic rate of oxygen consumption (CMRo2).

Two-point microrheology of inhomogeneous soft materials.
TLDR
A novel method for measuring the microrheology of soft viscoelastic media, based on cross correlating the thermal motion of pairs of embedded tracer particles, which yields accurate rheological data for highly inhomogeneous materials.
