Abstract
A system and method for intraoperative fluorescence imaging. A system for intraoperative fluorescence imaging includes a visible light source, a laser light source, a visible light image detector, a fluorescence image detector, radio frequency (RF) circuitry, and an image processing system. The RF circuitry is coupled to the laser light source and the fluorescence image detector. The RF circuitry is configured to modulate laser light generated by the laser source, and modulate an intensifier of the fluorescence image detector. The image processing system is coupled to the visible light image detector and the fluorescence image detector. The image processing system is configured to merge a fluorescence image produced by the fluorescence image detector and a visible light image produced by the visible light image detector to generate an intraoperative image showing an outline of a region of interest identified in the fluorescence image overlaid on the visible light image.
