Imagine that you are in a remote village somewhere with no medical clinic.Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong. Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic (诊断的) tool.
Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to correctly interpret what they see. With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.
His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.
By inventing a medical tool that uses existing technology—mobile phones—Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere. .
A. As a result, they may diagnose illnesses incorrectly.
B. People are trying to reduce the cost of this new medical tool.
C. This tool has become much more popular all around the world.
D. Another reason that Ozcan's invention is important is that it is inexpensive.
E. You become very sick and must wait days until a mobile medical unit arrives to help.
F. Ozcan's simple, cost-effective tool might just save millions of lives around the world.
G. Even though you may only have a simple infection, you might die because of the delay.
