We were asked by @acousticsorg to write an article to explain how super-resolution ultrasound works for a general audience, and it turned out to be quite a challenging (and FUN!) task! If you wonder what Fig. 2👇is about you can check out our paper here: acousticstoday.org/super-res…

It’s been an absolute honor and pleasure to co-teach the @IEEE_UFFC_Soc IUS “Super-Resolution Imaging” short course with Olivier Couture over the past two years. Excited to continue the course with @JeanProvost at IUS 2025 in Utrecht! – at Taipei City, Taiwan

🧵6/7 FRC analysis showed that high-frequency ULM (when combined with the new @verasonics NXT system that provides 125 MHz sampling frequency) achieved a spatial resolution of ~7.1 microns in mouse brain when using 2-sigma threshold.

🧵5/7 High-frequency ULM enabled us to observe intricate details of the cerebral microvasculature. In one instance, we were able to trace an MB traveling through a descending artery, making a U-turn in a capillary vessel, and moving back up through an ascending vein.

🧵4/7 At high MB concentrations, lower-frequency probes (L22 and L35) struggled with MB localization, leading to incomplete ULM images with many missing vessels. In contrast, the high-frequency probe (MS550S) produced a very high-quality ULM image with clear vessel delineation.

🧵3/7 At standard MB concentrations, higher imaging frequencies produce ULM images with sharper and more clearly delineated microvessels. Also the thinner slice thickness of high-frequency probes minimizes blurring in the elevational direction, resulting in “crisper” ULM images.

🧵2/7 Higher imaging frequency leads to smaller MB PSFs, which facilitate better MB separation and subsequent localization and tracking pipeline. Higher imaging frequency also supports the use of higher MB concentrations in blood stream to speed up ULM vessel filling.

🧵1/7 In this study led by @MRLowerison, we present high-frequency #ULM, which generated some of the best ULM images we've ever seen. In mouse brains with MB enhancement, SNR is not an issue and high frequency is ideal for ULM imaging. Full paper: biorxiv.org/content/10.1101/…

Totally blown away by my visit to Christine Démoré and Stuart Foster's labs at @Sunnybrook to serve as the external examiner for now Dr. Jing Yang. One of the best ultrasound research facilities on the planet: top-tier work + fantastic people! 🇨🇦 is a great place for ultrasound!
