alfred-yu.jpgUltrasound imaging is undoubtedly popular in today’s clinical practice. However, the current technology is known to have systemic limitations. Can we intuitively track complex flow with ultrasound? Can we consistently generate membrane pores with ultrasound? This seminar will introduce our laboratory's quest to devise high-frame-rate (>1000 fps) ultrasound flow imaging tools for vascular diagnostic applications and to apply advanced imaging tools for visualizing important wave-cell interactions in therapeutic ultrasound. Our ultrasound imaging innovations have enabled us to reveal complex vascular phenomena that arise in response to physiological stressors. Our cellular imaging investigations have unravelled various biophysical interactions between low-intensity ultrasound and living cells. A series of single-cell imaging findings will be presented, including the case where microbubbles are introduced as agents to induce acoustic cavitation.
