｜講者：Dr. Dong-Guk Paeng EJU NATIONAL UNIVERSITY Professor in Dept. of Ocean System Engineering
｜主題：From diagnostic ultrasound of arterial pulsatility to therapeutic ultrasound focusing on brain applications
This talk is about biomedical ultrasound to be applied to conventional diagnostic ultrasound and new-rising therapeutic ultrasound. After introducing the general diagnostic ultrasound areas emphasizing on emerging technologies, dynamic 3-dimensional motion of the arterial vessels and red cells in it observed by ultrasonic imaging would be shown with the interpretation of the observed phenomena. The significance and applications of the ultrasonic measurement of the dynamic motion of arterial vessels and its red cells would be discussed in terms of cardiovascular diseases and degenerative brain diseases.
Then the topic would be switched to therapeutic ultrasound, which started in 1930’s even before diagnostic ultrasound but has brought a new renaissance since 2000’s. Therapeutic ultrasound would be overviewed in terms of mechanisms and recent statistics of its expanding applications. Then brain applications of the focused ultrasound would be emphasized. The chances for researchers and students in the field of focused ultrasound would also be mentioned.
Dong-Guk Paeng received the B.S. and M.S. degrees in Earth and Marine Sciences from Hanyang University in Korea, in 1991 and 1993, respectively. He obtained another M.S. degree in Ocean Engineering
from Massachusetts Institute of Technology in 1997, and the Ph.D. degree in Acoustics program from the Pennsylvania State University in 2002. Dr. Paeng worked as research associate in Biomedical Engineering at the University of Southern California from 2002 to 2003 and 2007 to 2008 during his sabbatical year. He has been a professor of Ocean System Engineering and in the interdisciplinary postgraduate program of biomedical engineering at Jeju National University, Korea since 2003. He was the 1st Richard Merkin Fellow at Focused Ultrasound Foundation (FUSF) during his sabbatical year (2015-16) and has served as Asian ambassador of FUSF since then. He has been jointly appointed as a Research associate professor in the department of Radiation Oncology and Radiology and Medical Imaging at University of Virginia (2015-21). Now he is a visiting professor jointly appointed in Electrical Engineering and Medical Imaging departments at National Taiwan University (NTU) for fall semester in 2023. His research interests are in ultrasonic measurement and analysis of dynamic red blood cell aggregation and 3-dimensional vessel motion under pulsatile flow, high-frequency ultrasound applications, and brain applications of therapeutic ultrasound.
