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.read more

Visible Reflectance Hyperspectral Imaging: Characterization of a Noninvasive, in Vivo System for Determining Tissue Perfusion
TL;DR: A visible reflectance hyperspectral imaging system for noninvasive, in vivo, quantitative analysis of human tissue in a clinical environment and a model of vascular dysfunction involving both ischemia and reactive hyperemia during tissue reperfusion is examined.
Patent
Multispectral biometric sensor
TL;DR: In this paper, an illumination subsystem provides light at discrete wavelengths to a skin site of an individual and a detection subsystem receives light scattered from the skin site, and a computational unit is interfaced with the detection system.
Patent
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.
