Innovations of ultrasound

Sound.  As music, it can evoke the feeling of a sentiment perfectly expressed. In the human and animal world, it is often the vehicle to provide comfort and social cohesion — or quickly communicate information needed for safety and survival. The ability to perceive sound is one of our key senses and its waves surround…

Ultrasound for the future

Ultrasound is one of the best-known medical imaging devices. It is safe, cost-efficient and relatively portable, making it one of the most accessible diagnostic and therapeutic medical technologies. And its potential goes far beyond what it is being used for today.

New tool uses ultrasound ‘tornado’ to break down blood clots

Researchers have developed a new tool and technique that uses “vortex ultrasound” – a sort of ultrasonic tornado – to break down blood clots in the brain. The new approach worked more quickly than existing techniques to eliminate clots formed in an in vitro model of cerebral venous sinus thrombosis (CVST).
In this illustration, an ultrasound transducer sends a wave that pushes against arterial walls and records the wave propagation.

Sound on

Humans use sound to see where our eyes can’t — like when you’re putting up a shelf and tap the wall to find the studs. Those sounds, traveling through waves, answer questions — is this where the stud is, or is this just drywall? Over the years, technologies like ultrasound have used these sound waves…
