Decubitus ulcers are a costly and widespread issue in healthcare today, that result from impaired blood flow in skin and underlying muscle and tissue. To address this need, a point of care multi-wavelength diagnostic imaging system has been developed to monitor hemodynamic processes via use of optical imaging of deep tissue. The resulting measurements demonstrate changes in light-tissue interaction to differentiate healthy and pathologic tissue without disturbing patients in a hospital setting. The identification of light source-detector illumination patterns uniquely map to spatial depths of tissue. The additional time dependent component, allows a novel four-dimensional analysis of tissue. The portable, noninvasive, and non-contact features provide quantitative in-situ measurements.
