Richard Satava, program manager for advanced medical technologies, has been a driving force bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and others 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 away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at a
A. he is looking at the cuts on a computer screen
B. the cuts can be examined from different angles
C. the cuts have been highly magnified
D. he is wearing 3-D glasses
