Diffuse optical tomography for the detection of perinatal stroke at the cot side: a pilot study. Detection of cerebral ischemia in neurovascular surgery using quantitative frequency-domain near-infrared spectroscopy. Lin A. Spectral analysis of near-infrared spectroscopy signals measured from prefrontal lobe in subjects at risk for stroke. Biswal, B. In time domain imaging, the source is a sharp temporally focused beam and after penetrating the tissue it would broaden in time, this broadening is on the order of a few ns and depending on the source detector separation as well as tissue absorption and scattering properties.

Optical diffusion tomography by iterative-coordinate-descent optimization in a Bayesian framework. Diffuse optical tomography (DOT) is emerging as a viable new biomedical imaging modality present recent results of work on optical tomographic imaging in small animals  J. Norris, Senior Editor, Professional guide to diseases, 5th.
A limitation of this study is the lack of other physiological parameters acquired that could be correlated to the cerebral DOT signal.
It is called diffuse because the light propagates diffusely through any turbid medium such as biological tissues due to the effect of multiple and denes scattering property 2.

We investigated the utility of CW-DOT for early detection of perinatal stroke by studying interhemispheric patterns in these spontaneous low-frequency oscillations LFOs. Both commercial systems and academic research have been shown to be effective in tracking tumor protein expression and production, and tracking response to therapies.

This process is difficult and considered non-linear and ill-posed problem due to the diffuse and multiple scattering propagation of light in biological tissues. Diffuse optical imaging technique can be used to characterize biological tissues especially breast and brain tissues and predict some important information about tissue metabolism and many physiological changes in tissues, therefore, it can be employed in early detection of many abnormalities in tissue regarding blood contents or tissue oxygenation.
