By enabling more accurate cancer staging, the tool could save lives. “You end up with more suitable treatment plans,” says Jeremy Li, CEO and co-founder of Cision Vision, which launched InVision in April. It is already in major hospital systems across the country, including Stanford and Northwestern.
