Ultrasound scan and health check using your smartphone
Low-tech, relatively low-cost medical innovations are being showcased at an international health summit in Qatar.
One of the devices on show at the World Innovation Summit for Health is the "Smartphone Physical" developed by medical students at John Hopkins University in Baltimore and the University of Pennsylvania.
They have brought together a number of medical mobile phone applications to create a 10 minute physical examination.
It can check your heart rate and blood pressure, as well as test you for sexually transmitted infections.
The BBC's Global Health Correspondent Tulip Mazumdar tried it out for herself.
