Congrats to Robyn’s WIN Fellowship!
Jul 2021
Robyn Klassen has been selected as a recipient of the Waterloo Institute for Nanotechnology Fellowship for her work on ultrasound-mediated drug delivery and related biophysics investigations. Stay tuned for her presentation at this Fall's WIN celebration event!
Scholarship success for our new scholars
May 2021
Huge success for our lab in the scholarship arena this year! Congrats to William Pitman for his success in winning a Canada Graduate Scholarship in this round of competition. Di Xiao, Robyn Klassen, YanYan Tran, and David Hoskin have also been successful in their Ontario Graduate Scholarship applications. Well done everyone!
RESEARCH HIGHLIGHTS
Recent publications »Indulgence in Flow Phantoms
Jul 2019
Want to join our fun on designing flow phantoms? We have built walled phantoms of urethra, carotid bifurcation, and vessels with regional stiffness variations, as well as wall-less phantoms with omnidirectional flow and patient-specific geometries.
Cellular Bioeffect Investigation Protocol
Jun 2019
Our best practices in designing platforms to study the cellular bioeffects of LIPUS and sonoporation have now been published. Feel free to build similar platforms to study bioeffects such as ER stress, morphological repression, and cell-cycle arrest.
Doppler Ultrasound Bandwidth Imaging
May 2019
Ever wondered if flow instability can be visualized in flow diagnostics? Our new DUBI technique may provide an answer. It can track unstable flow at 10,000 fps. This is another imaging innovation after our previous success with VPI and CESI.
Open-Platform Ultrasound Scanner
Jan 2019
Our 2nd-gen high-frame-rate imaging platform is now ready! This software-based platform, with live imaging functionality that our 1st-gen platform didn't have, was done in collaboration with US4US in Poland. It has uniquely integrated our GPU innovations and our CESI technique.
The Classic: Adaptive Clutter Filtering
May 2018
Our classic work in eigen-based and SVD-based clutter filters has become very hot in ultrasound flow imaging. We have recently devised GPU-based eigen-filter algorithms and have conducted an ROC analysis on these adaptive filters.
