GoKawiilExplainer traces origins and mechanics of functional ultrasound brain imaging
A technical deep-dive explains functional ultrasound imaging (fUSI), a technique first demonstrated by Macé et al. in 2011, which rapidly captures video of blood-flow changes in brain tissue linked to neural activity. Unlike structural ultrasound's static images, fUSI isolates rapidly changing pixels to map vasculature, and the author describes researching the topic extensively, including reading a full ultrasound textbook, because technical details are scattered across application papers and specialized books.
