Titre : Image-Guided Surgery using Near-Infrared Light: Fundamentals and Clinical Applications

Résumé : There is a pressing clinical need to provide image guidance during surgery. Currently, assessment of tissue that needs to be resected or avoided is performed subjectively leading to a large number of failures, patient morbidity, and increased healthcare costs. Because near-infrared (NIR) optical imaging is safe, noncontact, inexpensive, and can provide relatively deep information (several mm), it offers unparalleled capabilities for providing image guidance during surgery. These capabilities are well illustrated through the clinical translation of fluorescence imaging during oncologic surgery. In this presentation we will review the fundamentals of NIR diffuse optical imaging and our translational efforts to provide image-guidance during surgery. We will present our latest results in fluorescence and oxygenation imaging for real-time monitoring and guided surgical intervention. We will also introduce our latest imaging platforms that combines two complementary NIR optical modalities, providing a comprehensive approach that allows the surgeon to identify problems and intervene in real time during surgery before irreparable damage occurs.

Biographie : Dr. Gioux is the director of the Biomedical Optics and Engineering Laboratory at the Beth Israel Deaconess Medical Center in Boston, MA. The focus of his work is to make a significant impact on healthcare by developing novel optical imaging and sensing technologies for clinical applications. In particular, Dr. Gioux is an expert on near-infrared fluorescence imaging and multispectral spatial frequency domain imaging (SFDI). He developed both techniques at a fundamental level and translated them from the bench to the bedside to provide intraoperative image-guidance to surgeons. Dr. Gioux received a M.S. in Electronics and Signal Processing from ENSEEHIT, France, a M.S. in Photonics from Boston University, and a Ph.D. in Biomedical Engineering from Boston University. He is now an adjunct assistant professor of Biomedical Engineering at Boston University and an assistant professor of Medicine at Harvard Medical School.
