Vascular surgeons of the David Grant USAF Medical Center watch as a robotic arm maneuvers into position to gather images during an abdominal aortic aneurysm procedure Oct. 14, 2010, in the cardiovascular operating room, Travis Air Force Base, Calif. The CT-type images delivered by the Artis Zeego are needed to guide physicians through arteries during tedious procedures, such as implanting stents to repair an abdominal aortic aneurysm.
