Abstract
Systems and methods for imaging the reflectance of a substrate, such as a tissue substrate, may include a light source, a light transport body configured to project light from the light source to an examination substrate and transmit light reflected by the examination substrate, and an analysis section in optical communication with the light transport body and having a reflectance avoidance imaging module and at least one of a reflectance spectrophotometry module and a fluorescence imaging module. Methods may include utilizing the microcirculatory flow information, oxygen availability information, and the adequacy of oxygenation of tissue cells information, making an early and sensitive determination regarding states of shock in patients.
