Multimodal Laparoscopic System for Biological Tissue Perfusion and Metabolism Assessment

Abstract

Due to the widespread introduction of laparoscopic studies into modern surgical practice, the task of objectifying the obtained data and expanding the opportunities for obtaining additional diagnostic information is urgent. In this work, we develop the first-of-its-kind multimodal laparoscopic system integrating hyperspectral, fluorescence, and laser speckle-contrast imaging with a commercially available 5-mm rigid laparoscope. We introduced an imaging system and conducted a feasibility study on phantoms and healthy volunteers.
