Sound Waves Being Used To Treat Strokes

Neurologists have built an ultrasound device which uses focused sound waves to destroy stroke-causing blood clots in brains. The procedure is non-invasive – requiring no drugs or surgery – and is already being tested on patients.

The machine and procedure allows doctors to “surround the head with an array of transducers that can focus ultrasound beams on a single spot in the brain without damaging the skull.” This means that diseased tissue could be destroyed without any collateral damage or risky surgery.
