Blast exposure is a prevalent cause of mild traumatic brain injury (mTBI) in military personnel in combat. However, it is more common for a service member to be exposed to a low-level blast (LLB) that does not result in a clinically diagnosable mTBI.

Conventional brain-imaging modalities may be limited by high cost, difficulty of bedside use, noncontinuous operation, invasiveness or an inability to obtain measurements of tissue function, such as oxygenation during stroke. Our goal was to develop

We develop a clinical visible-light spectroscopy VLS tissue oximeter. Unlike currently approved near- infrared spectroscopy NIRS or pulse oximetry SpO2%, VLS relies on locally absorbed, shallow-penetrating visible light 475 to 625 nm for the monitori

Background The authors evaluated the ability of visible light spectroscopy (VLS) oximetry to detect hypoxemia and ischemia in human and animal subjects. Unlike near-infrared spectroscopy or pulse oximetry (SpO2), VLS tissue oximetry uses shallow-pene

We report the development of a general, quantitative, and localized visible light clinical tissue oximeter, sensitive to both hypoxemia and ischemia. Monitor design and operation were optimized over four instrument generations. A range of clinical pr

We measured oxygenation of the brain in animals during changes in oxygen delivery (hypotension, shock). We found that such changes were measurable, and detected one change before the problem was clinically noted, thus suggesting that such methods may

We measured the changes in oxygenation of the brain in animals and humans during changes in oxygen delivery (hypotension, shock) or during brain activation (such as finger movement). We found that such changes were measurable. In addition, we found t

Using the unique spectral signature of each tissue type (e.g. liver differs from bowel), we performed automated discrimination among normal tissue types (e.g. nerve, artery, vein, muscle) in laboratory and clinical studies.

Each tissue has a unique spectral signature (e.g. liver looks distinct from bowel due to differences in both absorbance and in the way the tissue scatters light). Therefore, we suspect that automated discrimination among tissue types (e.g. blood, ner
