The Department of Homeland Security will begin installing the first of 150 full-body scanners in U.S. airports next week.
Boston's Logan International Airport will be the first, with three scanners scheduled for installation.
Officials plan to install another scanner at Chicago's O'Hare International in the next two weeks.
"The rest of the 150 machines that were purchased with $25 million from President Barack Obama's 2009 stimulus plan are expected to be installed in airports by the end of June," Homeland Security spokeswoman Amy Kudwa, said.
The push for scanners comes after terror suspect Umar Farouk Abdulmutallab managed to get past security in the Netherlands by hiding a bomb in his underwear in an attempt to blow up a Detroit-bound airliner.
The technology is supposed to allow screeners to see objects hidden under a person's clothing.
Other countries have also signed on. France is now using a full-body security scanner for U.S. bound passengers at Paris' Charles de Gaulle Airport.
