The U.S. Transportation Security Administration has tested a new, more modest body scanning system.
Tests on the new system were conducted at McCarran International Airport in Las Vegas, Nev.
It allows passengers who are being screened to see what the TSA agents see and it displays a more generic image in the form of a stick figure. If there is a threat, a red box will appear on the outline at the location of the object. If no threat arises, an "OK" will appear on the screen without an outline.
"We are always looking for new technology and procedures that will both enhance security while strengthening privacy protections," TSA Administrator John S. Pistole said in a statement.
The current scanners show detailed outlines of the person's body on a screen, but are viewed only by a second screener in a private room. The second screener then reports to checkpoint if they have found something suspicious.
"Testing this new software will help us confirm test results that indicate it can provide the same high level of security as current advanced imaging technology units while further enhancing the privacy protections already in place," Pistole said.
