Hyperspectral/multispectral imaging in determination, assessment and monitoring of systemic physiology and shock
First Claim
Patent Images
1. An apparatus for evaluating a local tissue of a subject, the apparatus comprising:
- an optical acquisition system configured to generate medical hyperspectral imaging data of a region of interest of the subject, wherein the optical acquisition system has a first field-of-view;
a diagnostic processor that receives the medical hyperspectral imaging data from the optical acquisition system;
at least one algorithm running on the diagnostic processor, wherein the at least one algorithm uses at least one of oxygenated, deoxygenated, and total hemoglobin levels based on the medical hyperspectral imaging data to quantify a clinical signal of the local tissue of the subject;
a display device configured to display the quantified clinical signal of the local tissue of the subject; and
an image projector having a second field-of-view that is precisely co-aligned with the first field-of-view, wherein the image projector projects a fiducial self-calibration pattern and the generated medical hyperspectral imaging data onto the region of interest in a visible spectrum wavelength range, whereinthe optical acquisition system is configured to read the fiducial self-calibration pattern projected onto the region of interest in order to achieve co-registration between the first field of view and the second field of view and map the generated medical hyperspectral imaging data onto the region of interest.

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 real-time 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.
