ABSTRACT:
Methods for optically imaging blood flow changes, blood flow characteristics and changes in the oxygenation of blood in an area of interest are disclosed. The area of interest is illuminated with electromagnetic radiation(emr) in the visible or infrared regions of the spectrum, and a control image representative of the emr absorption of the area of interest is acquired. A subsequent image representative of the emr absorption is compared to the control image to detect changes in the emr absorption that are indicative of changes in blood flow, changes in blood flow characteristics, or changes in blood oxygenation in the area of interest.
