Fluorescence-Guided Laparoscope with Microscopic Margin Analysis Capabilities for Surgical Guidance During Tumor Resection
This technology is a laparoscope that combines both white light and fluorescence imaging (WLFI) for wide field tumor localization and multiphoton microscopy (MPM) for microscopic surgical margin definition. The WLFI channel and MPM imaging channel are housed on an extendable arm on the laparoscope and images from both channels are displayed simultaneously...
