Low-cost ultrasound scanner unveiled in UK

Researchers in the UK have unveiled a low-cost ultrasound scanner that can be plugged into any computer or laptop to reveal vital information about the unborn child. The hand-held USB device, which is roughly the size of a computer mouse, costs just $65 to make – a far cry from most machines which can cost more than $300,000. Al Jazeera's Tarek Bazley reports.
