Abstract
Systems and methods for remote thermographic assessment of tissue viability are disclosed. A system may include a controllable source of one or more thermal stimuli to be applied to a tissue, a measurement system to measure a heat response of the tissue before, during, and/or after the application of the thermal stimuli, and an electronic device that may control either one or both of the source of thermal stimuli and the measurement system. The electronic device may also receive tissue thermal response data from the measurement system, and may further calculate a measure of tissue viability. A method of determining tissue viability may include supplying a thermal stimulus to a tissue, receiving, by a measurement device, the thermal response of the tissue to the stimuli, and a comparison of the thermal response data to at least some viability threshold values. The results may be displayed in a graphical manner.
