With Google’s announcement Thursday of the Body Browser, online mapping technology finally caught up with the medical crew of “Fantastic Voyage,” miniaturized in the 1966 sci-fi flick to enter a renowned scientist’s bloodstream and save his brain from a life-threatening blood clot. A Chrome-OS driven online Gray’s Anatomy, Body Browser continues Google’s quest to map everything, now including the human body. “Body Browser is a detailed, interactive 3D model,” said Google representative Jason Freidenfelds.
