| Richard Satava, program manager for
advanced medical technologies, has been a driving force in bringing virtual
reality to medicine, where computers create a "virtual" or simulated environment
for surgeons and other medical practitioners (从业者). "With virtual reality we’ll be able to put a Surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U.S. The surgeons would look at the soldier through virtual reality helmets (头盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier. Although Satava’s vision may be years A. will enable surgeons to be physically present on every battlefield. B. can raise the spirits of soldiers wounded on the battlefield. C. will greatly improve medical conditions on the battlefield. D. can shorten the time for operations on soldiers wounded on the battlefield.
