LAS VEGAS, NV - FEBRUARY 01: U.S. Transportation Security Administration supervisor Nick Fox (R) and another TSA employee demonstrate an advanced image technology (AIT) millimeter wave scanner using new Automated Target Recognition software being tested by the TSA at McCarran International Airport February 1, 2011 in Las Vegas, Nevada. The new software detects potential threat items and displays them on the outline of a generic body displayed on a monitor attached to the unit instead of using passenger-specific images. TSA officers will no longer need to use a remotely located room to view the images, which will make the process more efficient according to a TSA spokesman. (Photo by Ethan Miller/Getty Images) less
