TLDR
In this paper, a hyperspectral imaging system is used to demonstrate changes in tissue oxygen delivery, extraction and saturation during shock and resuscitation. But the system is not suitable for the monitoring of septic or burn shock.
Abstract
The present invention provides a hyperspectral imaging system which demonstrates changes in tissue oxygen delivery, extraction and saturation during shock and resuscitation including an imaging apparatus for performing real-time or near real­time assessment and monitoring of shock, including hemorrhagic, hypovolemic, cardiogenic, neurogenic, septic or burn shock. The information provided by the hyperspectral measurement can deliver physiologic measurements that support early detection of shock and also provide information about likely outcomes.

Method and apparatus for providing high contrast imaging

TL;DR: In this paper, an in vivo imaging device having an illumination system that creates a virtual source within a tissue region of a subject in a non-invasive manner is presented. And the illumination pattern is projected onto the object plane in a manner that maximizes the depth to which clear images of sub-surface features can be obtained.
