Abstract
Systems and methods for monitoring patients utilizing reflectance avoidance as well as other imaging modalities. Information regarding perfusion, oxygen saturation and oxygen availability, as well as others may be obtained. System embodiments 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. The light source may be pulsed in order to improve the quality of video images produced by the systems.
