    Plenary: Advances in ultrasound microvascular imaging - potential applications to HBO2?:
    Virginie Papadopoulou, PhD

    About the lecuture:

    This presentation focuses on new techniques for Papadopoulou imagemicrovascular imaging and perfusion quantification using contrast-enhanced ultrasound imaging (CEUS) that may be of interest in the context of HBO2. Microbubble ultrasound contrast agents (UCAs) have over two decades of use in echocardiography applications in the USA as well as non-cardiac imaging in the rest of the world. They are expected to increase in use with the FDA approving them for the first time in 2016 for non-cardiac applications in the USA, and the approval in 2017 of Current Procedural Terminology (CPT) codes opening the door to reimbursement. In particular, they offer advantages for longitudinal follow-up of patient response due to their lower adverse reaction rates than CT/MR contrast agents, relative inexpensiveness and non-radiation use. We review their current use in cardiovascular disease and oncological applications, as well as research advances in ultrafast, volumetric, and super-resolution imaging that can provide vascular and blood flow velocity maps at micrometer scale at multiple centimeters depth. We discuss clinical and preclinical research examples for how these techniques have been used to monitor and predict response to microvascular-remodeling therapy. We finish by illustrating their potential in image-guided therapeutic applications, such as opening the blood-brain barrier to enhance drug delivery, increasing tumoral, trans-epithelial or biofilm drug delivery, modulating tumor hypoxia, and enhancing sonothrombolysis and focused ultrasound surgery.

    About Dr. Papadopoulou:
    Dr Papadopoulou is an Assistant Professor at UNC Chapel Hill, North Carolina, USA. Her research aims to bridge the different areas dealing with bubbles in the bloodstream, from environmentally triggered endogenous bubbles, to engineered contrast agents for ultrasound imaging and therapy. She joined the laboratory of Prof. Paul Dayton at UNC Chapel Hill in 2016, where her research focuses on in vivo cancer imaging and therapy, as well as minimizing decompression stress from scuba diving. She works on assessing tumor neovascularization with novel ultrasound imaging techniques, optimizing trans-epithelial drug transport with acoustically-active nanodroplets and improving radiation therapy using oxygen microbubbles. She is also the 2017 recipient of the Divers Alert Network/Bill Hamilton Memorial Grant, awarded by the Women Divers Hall of Fame, for her on-going work translating state-of-the-art ultrasound microbubble imaging techniques to create a dynamic assessment of decompression bubbles. Previously, she worked in the laboratory of Dr Meng-Xing Tang at Imperial College London where she developed an ultrasound imaging prototype to acquire 3D vascular flow dynamics in healthy volunteers. She received her PhD in Bioengineering from Imperial College London in 2016, where her thesis focused on bubble formation, growth and circulation dynamics in vivo from hyperbaric decompression, relevant to scuba divers and astronauts to prevent decompression sickness. Concurrently as an EU-funded Marie Curie fellow and COST member, she spent time in Belgium working on hyperbaric physiology and in Greece on degassing bubble growth instrumentation.

    About CAPt Murphy:

    Captain Thomas P. Murphy was raised in Hopatcong, NJ. He graduated from State University New York Maritime College with a Bachelor of Science in Business  Administration and NROTC Commission in May 1993. He attended the Surface Warfare Officer School in Newport, RI, and the Basic Diving Officer and Salvage Officer courses in Panama City, FL. He reported to USS Whidbey Island (LSD-41) in February 1995, where he served as the Weapons, 2nd Division, Navigation and Assistant Operations Officer. He graduated from Naval Explosive Ordnance Disposal School and was designated an EOD Officer in Nov 1998. He was assigned to Explosive Ordnance Disposal Mobile Unit FIVE, Agana, Guam, where he served as The Officer-In-Charge of Detachment Three from 1998 to 2000. His Detachment was assigned to and deployed with Commander Amphibious Squadron Eleven aboard the USS BELLAWOOD (LHA-3). He and his team participated in Operation Stabilize in East Timor. He reported in December 2000 as Officer-In-Charge of Explosive Ordnance Disposal for The Mobile Unit Two Detachment, Yorktown, VA. He was personally responsible for providing regional EOD and Diving response as military support to Civil Authorities as well as in support of sensitive military incidents. During this tour he coordinated closely with multiple government agencies to include the Federal Bureau of Investigation (FBI) Norfolk field office, Virginia State Police and Newport News and Yorktown municipalities.  He was assigned as the Mine Countermeasures (MCM) Tactics / Exercise Department Head for the Commander of Mine Countermeasure Squadron One from January 2003 to May 2005. Additional responsibilities encompassed support for the 18 major fleet MCM shaping and Phase Zero operations in support of the Pacific Commands Strategic Cooperation initiatives between six countries within the 3rd and 7th fleet areas of operation. In September 2006, CAPT Murphy assumed duties as the Executive Officer of EOD Mobile Unit Eleven. As XO, he coordinated the deployment of 17 EOD platoons in support of operations Iraqi Freedom and Enduring Freedom during the global war on terror, which successfully executed over 2000 counter-iIED missions and destroyed over 40,000 lbs. of explosive remnants of war. In August 2008, he was assigned to the Chief of Naval Operations Navy Quadrennial Defense Review (QDR) Directorate as the Irregular Warfare Action Officer and later as cooperative security team lead for the CNO’s Naval Warfare Integration Directorate (N00X). In June 2010, he assumedcommand of Mobile Diving and Salvage Unit One (MDSU1) in Pearl Harbor, HI. CDR Murphy successfully deployed twice as Commander Task Group 56.1 and 56.9 where he led diving, salvage, and explosive ordnance disposal forces dispersed throughout the U.S. Naval Forces Central Command AOR and led a salvage response team in support of CTF 73 response to the USS GUARDIAN grounding on the Tubbataha Reef, Philippines. In July 2013, he was assigned as the Mine Countermeasures Squadron SEVEN CSO in Sasebo Japan. In August 2015, he was assigned back to the OPNAV Staff as the Deputy for Program Development for Unmanned Systems for Unmanned Warfare Directorate (OPNAV N99) and as Deputy for Urgent Needs and Accelerated Acquisition for Integrated Warfare Directorate (OPNAV N9I). CAPT Murphy is a graduate from the US Army Command and General Staff College, has an EMBA from Benedictine College, and a Master in National Resource Strategy from The Eisenhower School.
