Throughout my career, I have been fascinated by a fundamental challenge in surgery: how to provide surgeons with the most accurate and complete information possible while they are operating. In cranial and spinal procedures, where millimeters can separate successful outcomes from serious complications, surgical decision-making depends on precise knowledge of anatomy, pathology, and the constantly changing operative environment. Much of my research, clinical collaboration, and entrepreneurial work has been dedicated to addressing this challenge through advanced imaging technologies and fluorescence guidance systems that enhance the surgeon’s ability to see, understand, and navigate the surgical field.
My work in image-guided surgery began with the recognition that conventional surgical navigation systems have an important limitation. Most rely on preoperative imaging studies obtained before surgery begins. While these systems provide valuable guidance initially, the anatomy often changes significantly during the procedure. In cranial surgery, for example, brain tissue can shift once the skull is opened and tumor resection begins. Similarly, spinal procedures involve dynamic anatomical changes that can reduce the accuracy of navigation systems based solely on preoperative images. As a result, surgeons may be making critical decisions using information that no longer accurately represents the patient’s anatomy.
This challenge became a driving force behind the work that ultimately led to the formation of InSight Surgical Technologies. Our vision was to create a new generation of surgical navigation systems capable of continuously updating the surgeon’s map of the operative field. Rather than relying on static images acquired before surgery, we sought to develop technologies that could incorporate intraoperative data and computational modeling to maintain an accurate representation of anatomy throughout the procedure. This concept of image updating represents a significant evolution in surgical navigation and has the potential to dramatically improve surgical precision.
At InSight Surgical Technologies, we have focused on developing systems that augment the surgeon’s view of the evolving surgical field through real-time image updating and advanced visualization technologies. Our goal is to provide surgeons with continuously refreshed information that reflects what is actually happening inside the patient at every stage of the operation. Studies involving our image-updating technologies have demonstrated substantial improvements in navigation accuracy compared with conventional systems. While traditional navigation platforms may experience several millimeters of error as surgery progresses, image-updating approaches can maintain significantly higher levels of accuracy throughout the procedure. This capability is particularly important in neurosurgery, where preserving healthy tissue while maximizing tumor removal directly influences patient outcomes.
Another area that has been central to my work is fluorescence-guided surgery. Fluorescence guidance offers surgeons an entirely new way of visualizing disease. By administering fluorescent agents that accumulate within tumors or highlight specific tissue characteristics, surgeons can visualize structures that may not be readily apparent under standard operating room illumination. During surgery, specialized imaging systems detect the fluorescent signal and provide enhanced contrast between tumor and normal tissue. This capability helps surgeons identify disease more accurately and perform more complete resections while preserving critical anatomical structures.
At InSight Surgical Technologies, we view fluorescence guidance as a natural complement to image updating. While image updating provides accurate anatomical navigation, fluorescence imaging adds biological information about the tissue itself. Together, these technologies create a more comprehensive understanding of the surgical environment. Surgeons gain access not only to where structures are located but also to information about tissue composition, tumor boundaries, and physiological characteristics. This combination of anatomical and molecular guidance represents a significant advancement toward truly intelligent surgical systems.
The broader vision extends beyond simply improving visualization. I believe the future of surgery lies in the creation of dynamic digital representations of the operative field that continuously integrate imaging, sensing technologies, computational modeling, and artificial intelligence. At InSight Surgical Technologies, we are developing platforms designed to support this future by providing real-time, machine learning-enhanced intraoperative guidance that can help surgeons navigate increasingly complex procedures. These systems are intended to improve accuracy, reduce invasiveness, personalize treatment strategies, and ultimately enhance patient outcomes.
One of the most rewarding aspects of this work has been witnessing the convergence of engineering, computer science, imaging physics, and clinical medicine. Advances in surgical technology do not emerge from a single discipline. They require multidisciplinary teams capable of translating scientific discoveries into practical clinical tools. My experiences at Dartmouth and through InSight Surgical Technologies have reinforced the importance of these collaborations in driving innovation and bringing transformative technologies into the operating room.
Looking ahead, I believe we are entering a new era of digital surgery. Image updating, fluorescence guidance, artificial intelligence, and autonomous computational systems will increasingly work together to support surgical decision-making. Surgeons will have access to continuously evolving maps of patient anatomy, enhanced visualization of disease, and predictive guidance based on vast amounts of clinical data. These technologies will not replace surgeons; rather, they will empower them with unprecedented information and precision.
Ultimately, the goal has always been straightforward: to help surgeons perform safer, more effective procedures and to improve outcomes for patients facing some of the most challenging diseases. Through the continued development of advanced imaging technologies and fluorescence guidance systems, I believe we are moving closer to a future where surgical interventions are more precise, less invasive, and more successful than ever before.
