Non-Invasive Tissue Oxygenation Measurement Systems. Phase 1.
Abstract
The Phase I program carefully identified and defined the problem of noninvasive sensing of deep tissue oxygenation. Existing technology was assessed in light of the requirements needed to meet the Army objectives for a sensor system that integrates into a much larger effort to equip the foot soldier of the future with advanced protective capabilities. An approach based on diffuse reflectance tomographic imaging was identified as having the potential to meet the objectives of the sensor development initiative being sponsored by the U.S. Army. Diffusive tomography in the context of this application would generate an image of the absorption characteristics of the irradiated skeletal muscle. When the imaging wavelength is matched to the absorption of hemoglobin and myoglobin the resulting image would reflect the state of oxygenation in the tissue. The power of the method is the ability to process the detected light signal to determine the spatial origin thus surface and deep tissue information can potentially be resolved. A program for developing this approach was proposed to the U.S. Army sponsor.
