Following this, the electrons in the excited state rapidly relax to the lower energy level within a few pico-seconds. This figure illustrates a case in which a close deep margin was detected using fluorescence imaging. We hypothesize that real-time fluorescence imaging can enhance intraoperative decision making by aiding the surgeon in detecting close or positive margins and visualizing unanticipated regions of primary disease.
