Therapeutic Laser Applications (BA)

Therapeutic Laser Applications

AudienceThis group focuses on the use of lasers in surgery or in other treatments of disease. This includes the use of lasers as surgical tools for tissue cutting, welding, and coagulation, as well as the use of optics to initiate cell-damaging photochemical reactions for the treatment of diseases such as cancer. In addition, optics, spectroscopy, and imaging provide unique tools that may allow real-time diagnostics of the efficacy of clinical procedures. For many of these applications, the development of optical tools for appropriate light delivery, especially for fiber-based or endoscopic delivery to tissues that are not directly accessible, is critical. In addition, this group emphasizes basic science studies of the mechanisms by which light can affect tissue in adverse or therapeutic ways.

OSA Therapeutic Laser Applications Technical Group Special Talk: Listening to the Sound of Light to Guide Surgeries

When: 14 April 2021, 14:00 - 15:00 PDT (UTC -7:00)

Join us at the OSA Biophotonics Congress for a special talk from Muyinatu Bell, the founder and director of the Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab at Johns Hopkins University, about her work in photoacoustic-guided surgery.

Photoacoustic 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. Dr. Bell’s talk will highlight novel light delivery systems, new spatial coherence beamforming theory, deep learning alternatives to beamforming, and robotic integration methods, each pioneered by the 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 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.

About Our Speaker:

Muyinatu Bell is the John C. Malone 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) and the SPIE Early Career Achievement Award (2021).
