This iPhone-based ultrasound machine can detect cancer

A novel iPhone-based portable ultrasound machine that can help detect cancer easily at home has been developed by US researchers.

The device called Butterfly IQ is a scanner of the size of an electric razor that can display black-and-white imagery of the body, when paired with an iPhone.

Developed by Connecticut-based start-up Butterfly Network, the pocket sized device works by shooting sound into the body and capturing the echoes.

On his smartphone, to which the device is connected, black-and gray images quickly appeared.

He found a 3 cm mass that was diagnosed as squamous-cell cancer — a form of skin cancer that develops in the cells of the outer layer of the skin.

Instead of vibrating crystals, Butterfly IQ uses “capacitive micro-machined ultrasound transducers”, or CMUTs, tiny ultrasonic emitters layered on a semiconductor chip a little larger than a postage stamp.
