Ultrasound is an old technology, with roots in the sonar scanners used during the Second World War. For decades, it’s been used mainly to inspect fetuses while they’re still in the womb, and to examine diseased hearts. But, in the past few decades, rapid advances in computer technology have transformed ultrasound into a powerful diagnostic instrument for everything from damaged organs to tuberculosis. If advancements in A.I. and telemedicine continue, patients could be given their own ultrasound machines to monitor chronic conditions at home. This approach is currently being tested 250 miles above Earth’s surface, where crew members aboard the International Space Station are using ultrasound to assess themselves for eye injuries, fractures, and other ills.
