Talk Abstract: My laboratory develops light-based technologies for imaging and sensing in the central nervous system. Here I discuss three exemplary projects in my laboratory in various domains.
-First, in the basic research domain, I describe efforts to develop longer wavelength Optical Coherence Tomography (OCT) at 1300 nm, 1700 nm, and even 2200 nm to image blood flow, vascular, and cellular architecture in deep cortical and sub-cortical layers non-invasively in rodents.
-Second, in the clinical ophthalmic research domain, I describe efforts to develop and optimize visible light OCT for ultrahigh resolution retinal imaging in human subjects. I demonstrate human imaging of retinal inner plexiform layer lamination, potentially a biomarker of dendritic changes in glaucoma, and Bruch's membrane, ground zero for the earliest changes in age-related macular degeneration.
-Third, in the experimental technology domain, I describe our novel approach to diffuse optical measurements of the human brain that uses interferometry. Using CMOS sensors for detection, we have demonstrated a reduction in cost of optical cerebral blood flow (CBF) measurements by two orders of magnitude over conventional techniques. I envision implications of this technology, which include high performance continuous CBF monitoring in neurointensive care, low-cost cell phone based CBF monitors for consumers, and better optical brain computer interfaces.
About Speaker: Vivek Srinivasan is Associate Professor of Radiology and Ophthalmology at the NYU Grossman School of Medicine. His group develops new light-based technologies for in vivo imaging and sensing of the brain and eye. Starting with a firm grounding in neurophysiology and biomedical engineering, his group employ ideas novel photonic technologies and approaches to accomplish this goal.
