Abstract:  Optical coherence tomography (OCT) is an interferometric imaging technology that enables micrometer-level resolution of tissue structure below the surface of optically dense tissues.  Since imaging was first demonstrated by researchers at MIT and MIT Lincoln Labs nearly two decades ago, optical coherence tomography (OCT) has developed rapidly to become an important clinical imaging modality in ophthalmology and coronary intravascular imaging.  The applications of OCT in biomedical research are now widespread and work continues toward clinical applications in other medical specialties.  This talk will begin with an introduction to the basic principles that underlie OCT signal generation and acquisition.  The classical time-domain methods on which the first instruments were based will be discussed along with newer Fourier-domain methods that allow high-speed operation without loss of signal integrity.  Novel operating modes, such as polarization-sensitive OCT and optical coherence elastography, will be also be introduced.  Finally, coronary imaging with OCT will be presented as a specific example of a clinical application which has recently gained attention following FDA approval and release of the first products into the market.


Biography:  Dr. Schmitt is currently Vice President of Research and Development at LightLab Imaging, a St. Jude Medical company.  Dr. Schmitt received the B.S. degree in biomedical engineering from Case Western Reserve University and the M.S. and Ph.D. degrees in electrical engineering from Stanford University.  After serving as Biomedical Engineering Coordinator for a non-profit health-care foundation in China for two years, he co-founded a laboratory at the U.S. National Institutes of Health, where he worked as a Senior Staff Fellow.  Dr. Schmitt joined the Hong Kong University of Science and Technology (HKUST) in 1994 as Associate Professor in the Department of Electrical Engineering, where he also served as the Co-Director of the Center for Medical Diagnostic Technology.  He left HKUST in 1998 to develop non-invasive optical technologies for patient monitoring at Nellcor Puritan-Bennett in Pleasanton, CA.  He joined LightLab Imaging, Inc., in 2000 and served as Chief Technology Officer until it was acquired by St. Jude Medical in 2010.
