The use of deep-tissue multiwavelength imaging is of paramount importance in clinical settings as a noninvasive solution to identify and monitor the progression of decubitus ulcers. A point-of-care multiwavelength imager is being developed, whose utility results from the provision of important physiological characteristics and blood flow metrics via analysis of deep-tissue response to light. The noninvasive real-time monitoring and analysis of tissue focusing on wound imaging is integral, because it allows for quantitative in situ measurements that characterize tissue to assess the progress of either tissue healing or necrosis.

    ABSTRACT: 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.
