Combination absorption and fluorescence for detection of vessels in intestinal sub-mucosa (Conference Presentation)

Paper Abstract

Injuries to main vascular structures within the sub mucosa present a serious complication during surgery. There is no evidence-based treatment to prevent this type of injury, so detection is critical. Using a combination of absorption and fluorescence imaging we can detect blood vessel phantoms to a depth of 7 mm in intestinal sub-mucosa. Using an illumination source at 850, and reading the cross-polarized reflected signal also at 850 gives the absorption image. Simultaneous excitation of ICG at 785 nm creates a fluorescent response that is used for contrast enhancement.
