Ultrasound on the battlefield

And no, it's not because they let women into the army. :p

BBC - "The US military plans a portable device that uses focused sound waves to treat troops bleeding internally from wounds sustained on the battlefield.

Ultrasound can seal ruptured blood vessels deep within the body without the need for risky surgery."

"The device would first use ultrasound imaging technology, in particular "Doppler ultrasound", to locate internal bleeding. This employs a physical phenomenon known as the Doppler effect to look for a characteristic signature of bleeding vessels.

It would then deliver a focused beam of high-powered ultrasound to those sites in order to cauterise the damaged vessels. "
