Using AI to Detect Cancer, Not Just Cats

Shaokang Wang and his startup, Infervision, build algorithms that read X-ray images and identify early signs of lung cancer. The company's technology, Wang says, is already running inside four of the largest hospitals in China. Two are merely running tests, but according to Wang, the two others--Shanghai Changzheng and Tongji, both in Shanghai--are installing the technology across their operations. "It's installed on every doctor's machine," he says. To what extent these doctors are actually using the technology is another question.
