Burying his face in a 3-D viewing system, Volkmar Falk of the Leipzig Herzzentrum (Germany's most important cardiac center) explores the chest cavity of a cadaver with the da Vinci robotic surgical system. Thomas Krummel (standing), chief of surgery at Stanford University's teaching hospital, observes the procedure on a monitor displaying images from a pair of tiny cameras in one of the three "ports" Falk has cut into the cadaver. From the book Robo sapiens: Evolution of a New Species, page 176.
