Abstract
This invention relates generally to an index map comprising both pressure and perfusion information from a diabetic patient foot for the purpose of treatment. The index map may also be a map of perfusion and/or metabolism of the tissue (reflecting oxygen delivery and oxygen extraction, obtained by thermal imaging, hyperspectral imaging, or duplex ultrasound, MRA, CT or laser Doppler imaging. This information aids treatment in prevention of diabetic foot ulceration and amputation and in treatment of tissue compromise to prevent tissue loss in other body regions.
Claims34
A method comprising:
- (A) determining a physiological state of a tissue of a subject by using a hyperspectral imaging device to collect tissue oxygenation, tissue oxygen extraction, tissue metabolism, or tissue perfusion information of said tissue;
- (B) determining a pressure applied to said tissue;
- (C) identifying an area of the tissue at risk for disease formation or disease progression based on the physiological state of the tissue or corresponding aspects of the pressure applied to the tissue;
- and
- (D) modifying the pressure applied to the at risk tissue,
- wherein identifying an area of the tissue at risk for disease formation or disease progression includes comparing changes in oxygenation levels of the tissue over a period of time.
