BBC News reports that scientists of The University College London developed a portable brain scanner that uses Bluetooth radio technology. This could lead to stroke victims receiving treatment much more quickly.

The scanner would send the images via Bluetooth - which swaps data via short-wave radio - to a computer onboard the ambulance to allow paramedics to diagnose the cause of the stroke, or send it to consultants at the hospital if they are unable to identify it.

The Stroke Association called the project “promising”.
