A group of medical consultants in Belfast have helped to develop a global mobile app that can identify where a doctor is going wrong when interpreting X-rays, reports the BBC.
Nearly 10,000 doctors around the world are said to be already using the app.
Dr Tom Lynch, head of nuclear medicine, at the Northern Ireland Cancer Centre, said the Experior app is being used in accident and emergency and cancer departments, but could be rolled out across all health specialities.
In a demonstration to the BBC, Lynch displayed 30 different X-ray images on an iPad, each displaying a particular condition.
The doctor's task, said Lynch, is to identify the diagnosis from the images, submit their answer and have it marked.
Pointing at the screen in the demo, Lynch told the BBC: "For instance, this X-ray shows a fractured jaw. This one shows a mass in the upper part of the chest. Another a hairline fracture in the skull.
"Some are obvious, some aren't. But they are typical X-rays that a junior doctor and one who's been qualified a long time would see in an emergency department."
The testing and training tool can be used to improve the decisions made by junior doctors, letting them know where they have gone wrong, he said.
Lynch said: "We already have doctors as far away as Australia and New Zealand using our app. Doctors can be learning wherever they're based and can study at home or at the hospital. Nearly 10,000 doctors are already using the Northern Ireland-developed app."
