While common in every doctor’s office and hospital in the developed world, ultrasounds haven’t been around very long. Ultrasound technology and machines have only existed in medicine for less than a century and weren’t perfected until the late 1950s. And, like all medical advancements, ultrasounds didn’t appear overnight. It took inventors and physicists many years to develop ultrasound. From simple experiments on bats to wartime sonar for tracking submarines to a rough prototype of the Logiq E9 made in Scotland, one breakthrough after another kept the technology advancing. Eventually, all these creations would lead to the ultrasounds we know today.

The understanding and treatment of brain function and neurological disorders took a step forward with findings from a study of piezoelectric nanoparticles stimulated by low-intensity pulsed ultrasound.
