It all started when Augmedics CEO Nissan Elimelech got a superhero-inspired idea: Wouldn’t it be cool if surgeons had X-ray vision? Several years of R&D produced the next best thing: xvision, a headset that uses augmented reality to turn a patient’s CT scan into a 3-D visualization that helps guide a spinal surgeon through operations in which every millimeter counts. The headset superimposes a 3-D image of a patient’s spine over their body, allowing surgeons to (almost) see what’s under the skin without ever looking away from the operating table. Cleared by the FDA in December 2019, the device is already in use at top U.S. hospitals like Johns Hopkins and Rush University Medical Center. —Jamie Ducharme
