Sonosite

In 1994, a company called ATL Ultrasound began work on a miniaturized ultrasound device for diagnostic imaging. That business eventually morphed into the Handheld Systems Business Group, which in turn was spun out as Sonosite in 1999. The company focuses on portable and hand-held ultrasound devices, offering “imaging performance typically found in costly ultrasound machines weighing more than 300 pounds in a system that is approximately the size and weight of a laptop computer,” according to its website. Fujifilm Holdings bought Sonosite for $1 billion in April 2012.
