From selfie taker to lifesaver: The smartphone grows up

As the smartphone falls in price while its capabilities improve, it is becoming a valuable tool in the diagnosis of a growing number of diseases and ailments around the world. When Yonatan Adiri's mother fell down a bank and briefly lost consciousness when travelling in China, an initial diagnosis suggested she had a few broken ribs, but nothing more serious. Doctors were keen to fly her to Hong Kong for treatment. But Yonatan's father was worried and took photos of the CT [computerised tomography] scans of the injuries, emailing them to his son. Yonatan showed the images to a trauma doctor, who instantly diagnosed a punctured lung.
