Ñݽ²Õß¼ò½é£ºWei-Ning Lee received her B.S. and M.S. degrees in electrical engineering from National Taiwan University, Taipei, Taiwan, R.O.C., and her Ph.D. degree in biomedical engineering from Columbia University, New York, USA. She then worked as a postdoctoral fellow at Institut Langevin in ESPCI ParisTech, Paris, France from January 2010 to June 2012. She then joined as an assistant professor with the Department of Electrical and Electronic Engineering at The University of Hong Kong and is now associate professor. She won a New Investigator Award at the American Institute of Ultrasound in Medicine (AIUM) Annual Convention in 2009 and an Early Career Award from the Hong Kong Research Grands Council in 2013.

½²×ùÌáÒª£ºUltrafast ultrasound imaging of the heart has emerged in recent years, enabling measurement oftransient dynamics inside the heart, such as myocardial deformation, electromechanical waves,and chamber blood flow. However, existing transthoracic ultrafast ultrasound imaging techniquesare based on pulsed and unfocused ultrasound waves for significance increase in frame rates, andtherefore they suffer from limited sonographic signal-to-noise ratio (SNR) and penetration due tothe insufficient delivery of ultrasound waves through the chest wall to interrogate the entire heart.In this talk, I will introduce our latest development of an unprecedented ultrafast ultrasoundcascaded-wave synthetic aperture (CaSA) imaging method, whose core is a specially-encodedtransmission and reception model, to achieve superior SNR and thus greater penetration at framerates higher than 3000 frames per second to map myocardial motion and chamber blood flow withhigh quality.
