China have invented a "deep learning" algorithm that can determine an individual's risk of heart disease by being shown just four photos of them.
The algorithm needs more refinement before it can be rolled out as a useful diagnostic tool, but experts say it has the potential to "revolutionise medicine" — but there are significant ethical hurdles to clear first.Between 2017 and 2019, researchers photographed 5,796 patients who had gone to hospital for heart imaging procedures.
Four images were taken of each patient — one full-frontal, two side profiles and one looking down at the top of the head.A deep learning algorithm was trained to analyse the four images and assess each person's risk of heart disease.
