As Covid-19 surges, researchers amass lung scans to build AI systems for patient care
At first, the images of lungs infected by the novel coronavirus were hard to come by. It was early in the pandemic, and Joseph Paul Cohen, a researcher at the University of Montreal, was trying to stockpile radiology scans to train an artificial intelligence model to recognize warning signs of severe illness.
With so few images available, the work was next to impossible. But in recent weeks, the resurgence of Covid-19 in the U.S. and other hotspots has solved that problem, allowing him to amass hundreds of lung scans from clinical reports published around the world. “We’re at a good number now,” said Cohen. “There’s a sufficient amount to start doing this.”
