Abstract
Appropriate assessment of wound oxygenation is critical to establish a diagnosis, to monitor the effect of the treatment, to guide the therapeutic process, to identify the presence of infection, and to predict the treatment outcome. Embodied systems and methods represent an enabling technology for noninvasive and objective assessment of wound tissue oxygenation. In addition to wound healing, disclosed embodiments offer low cost and portable avenues for noninvasive assessment of multiple clinical parameters for the detection and intervention of various malignancies in multiple soft tissue systems.
