Description

Abstract Intelligent intraoperative display of anatomic and physiologic information coupled to real time situational awareness to critical tissues will benefit all surgeryThe current surgical vision is limited to naked human eyes in open surgery or more recently using laparoscopic digital imaging for minimally invasive surgery and robot assisted surgeryIn laparoscopic visionalthough the visualization of surface anatomy and tissue physiology in the surgical field of view has been enhanced by recent advances in optical imaging technologythe imaging paradigm still remains passive and still poses a significant challenge due to the inherent narrow peripheral vision and limited depth perceptionWe propose the next generation laparoscopic vision system that provides intelligent display of unrecognized tissue structures to human eyesOur proposed use of a new paradigm and surgical vision technologycalled ISVisionTMequipped with modular plenopticD Color HD camera and snapshot NIR hyperspectral imagerwill permit a clear visualization of the critical target tissue of interestsurrounding anatomy into the operative fieldand situational awareness for both the tool and tissue to the surgeonOur Phase I effort comprises of engineering the clinically viable ISVision platform and testing the performance of its intraoperative useSpecificallythe ISVision system will clearly and precisely identify different tissue characteristicsaccurately displaying physiologic information including tissue perfusion and blood flowFollowing the Phasewe anticipate undertaking a Phase II projectduring which we will develop a clinical grade ISVision system and investigate its performance and utility in the operating roomWhile the initial focus of the Phase I and II effort is on the complex surgery such as liver resection due to crucial nature of critical sub surface structures located underneath liver hilum and parenchymathe ISVision system will potentially play an enabling role in all surgeries and establish it as a vital component of the operating room of the future
