SUMMARY:Dr. Christoph Hitzenberger\, Ph. D.
DESCRIPTION:From Ocular Biometry to Cellular Resolution – and Multifunctional OCT – Coherence Ranging and Imaging in the Human Eye over 35 Years \nAbstract \nIn the mid 1980s\, first applications of low coherence interferometry (LCI) to tissue metrology and analysis were reported. Starting from one-dimensional ocular biometry\, the technology has evolved into a high-speed\, 3-dimensional imaging technology\, now known as optical coherence tomography (OCT)\, with a multitude of functional extensions that has revolutionized ocular diagnostics. This talk illustrates the evolution of the technology over a third of a century\, as seen from a Viennese perspective. Starting with first axial eye length measurements by LCI\, a bridge is spanned to modern high-speed\, high-resolution\, and multifunctional OCT\, including some examples of current research in the OCT labs at Medical University of Vienna. \nBiography \nChristoph K. Hitzenberger is Professor of Medical Physics and Vice Chair of the Center for Medical Physics and Biomedical Engineering\, Medical University of Vienna\, and Editor-in-Chief of Biomedical Optics Express. He works in Biomedical Optics since 1987 and is one of the pioneers of low coherence ocular biometry and optical coherence tomography. Among his most important contributions to these fields were the introduction of the optical A-scan in 1990\, the first demonstration of Fourier domain OCT methods in 1995\, and pioneering work in polarization sensitive OCT since 2000. He is Fellow of OSA and of SPIE; his pioneering contributions to OCT were awarded with the Russ Prize of the US National Academy of Engineering in 2017 and with the Austrian Cross of Honour for Science and Art\, First Class. \n  \nREGISTER HERE \n  \nSponsored by the Michael and Roberta Berns Laser Microbeam Program

SUMMARY:Muyinatu Bell.\, Ph.D.
DESCRIPTION:Assistant Professor & PULSE Lab Director – Johns Hopkins University \nDepartment of Electrical and Computer Engineering\nDepartment of Biomedical Engineering \nListening to the Sound of Light to Guide Surgeries \nAbstract\nPhotoacoustic imaging offers “x-ray vision” to see beyond tool tips and underneath tissue during surgical procedures\, yet no ionizing x-rays are required. Instead\, optical fibers and acoustic receivers enable photoacoustic sensing of major structures – like blood vessels and nerves – that are otherwise hidden from view. The entire process is initiated by delivering laser pulses through optical fibers to illuminate regions of interest\, causing an acoustic response that is detectable with ultrasound transducers. Beamforming is then implemented to create a photoacoustic image. In this talk\, I will highlight novel light delivery systems\, new spatial coherence beamforming theory\, deep learning alternatives to beamforming\, and robotic integration methods\, each pioneered by the Photoacoustic & Ultrasonic Systems Engineering (PULSE) Lab to enable an exciting new frontier of photoacoustic-guided surgery. This new paradigm has the potential to eliminate the occurrence of major complications (e.g.\, excessive bleeding\, paralysis\, accidental patient death) during a wide range of delicate surgeries and procedures\, including neurosurgery\, cardiac catheter-based interventions\, liver surgery\, spinal fusion surgery\, hysterectomies\, biopsies\, and teleoperative robotic surgeries.  \nBiography\nMuyinatu Bell is an Assistant Professor of Electrical and Computer Engineering\, Biomedical Engineering\, and Computer Science at Johns Hopkins University\, where she founded and directs the Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab. Dr. Bell earned a B.S. degree in Mechanical Engineering (biomedical engineering minor) from Massachusetts Institute of Technology (2006)\, received a Ph.D. degree in Biomedical Engineering from Duke University (2012)\, conducted research abroad as a Whitaker International Fellow at the Institute of Cancer Research and Royal Marsden Hospital in the United Kingdom (2009-2010)\, and completed a postdoctoral fellowship with the Engineering Research Center for Computer-Integrated Surgical Systems and Technology at Johns Hopkins University (2016). She is Associate Editor-in-Chief of IEEE Transactions on Ultrasonics\, Ferroelectrics\, and Frequency Control (T-UFFC)\, Associate Editor of IEEE Transactions on Medical Imaging\, and holds patents for short-lag spatial coherence beamforming and photoacoustic-guided surgery. She is a recipient of multiple awards and honors\, including MIT Technology Review’s Innovator Under 35 Award (2016)\, the NSF CAREER Award (2018)\, the NIH Trailblazer Award (2018)\, the Alfred P. Sloan Research Fellowship (2019)\, the ORAU Ralph E. Powe Jr. Faculty Enhancement Award (2019)\, and Maryland’s Outstanding Young Engineer Award (2019). She most recently received the inaugural IEEE UFFC Star Ambassador Lectureship Award (2020) from her IEEE society. \n  \nREGISTER HEREDr. Muyinatu Bell\, Ph.D. \n  \nSponsored by the Michael and Roberta Berns Laser Microbeam Program
