In optical tomography, conventionally the diffusion approximation to the radiative transport equation (RTE) with a constant refractive index is used to image highly scattering or turbid media. Diffusion optical tomography with a constant refractive index is rather difficult due to the exponential instability of the inverse problem. Therefore, it is beneficial to find a simple yet stable model that adequately describes the physics of radiative transport, for example, refractive index based…

Bioluminescence tomography for media with spatially varying refractive index
Biomedical imaging has developed into the level of molecular imaging. Bioluminescence tomography (BLT), as an optical imaging modality, is a rapidly developing new and promising field. So far, much
Scaling property of the diffusion equation for light in a turbid medium with varying refractive index.
TLDR
It is shown that the process of photon diffusion in a turbid medium with varying refractive index and curved photon paths can be mapped to the diffusion process in a medium with straight photon paths and modified optical properties.
Approximation of Internal Refractive Index Variation Improves Image Guided Diffuse Optical Tomography of Breast
TLDR
Effective usage of image guidance by incorporating the refractive index (RI) variation in computational modeling of light propagation in tissue is investigated and a priori knowledge of the RI for the segmented regions of tissue in IG-DOT leads to more accurate estimates of optical properties.

Determination of the refractive index of highly scattering human tissue by optical coherence tomography.
TLDR
Two new techniques, based on optical coherence tomography (OCT), for determining the refractive index of highly scattering human tissue are described, using OCT to track the focal length shift that results from translating the focus along the optic axis within the tissue.
