Wednesday, April 28, 2021 12:10 pm - 1:00 pm EDT (GMT -04:00)

In this regular series, University of Waterloo Professors present their research in medically relevant areas to practicing clinicians from Grand River Hospital

About this Event

The February 2021 session hosts Professor Jason Au and his work on imaging vector flow in bifurcations.

Conventional vascular ultrasound is restricted to one-dimensional blood flow information, where we can observe fluid moving either towards or away from the ultrasound probe. While colour Doppler and spectrogram information are useful to observe fluid reflux or overall disturbed blood flow, traditional methods provide limited quantifiable information about complex blood flow conditions that may be relevant for basic and clinical human physiology. In this talk, Dr. Jason Au (Assistant Professor, Department of Kinesiology, University of Waterloo) will overview the latest developments in ultrasound techniques to visualize and quantify ‘complex’ blood flow information, and present initial findings from preliminary in vivo studies employing vector flow imaging techniques in the peripheral vasculature. Topics will include: a basic primer on ultrasound techniques, the oscillatory shear stress theory of vascular dysfunction, special cases of arterial bifurcations, and a discussion on upcoming opportunities to get involved in research with the above techniques.
