HEBRON, KY (FOX19) - Passengers at the Cincinnati/Northern Kentucky International Airport will now pass through full body scanners at security checkpoints.
CVG becomes the fourth airport in the country to use the screening technology, which has been the subject of controversy due to its invasive capabilities.
Some privacy advocacy groups claim the technology goes too far with its imaging, which produces a detailed outline of passengers' bodies.
TSA officials say the images blur certain features to ensure privacy, and passengers who are uncomfortable with the process have the option to be patted down by a TSA agent.
The new machines are among 150 bought with money from the federal stimulus package signed into law by President Barack Obama last year.
Deployment of the machines was announced in the fall, before a Nigerian allegedly tried to blow up a Detroit-bound airliner on Christmas Day with explosives concealed in his underwear.
That event highlighted the need for additional security in the U.S. aviation system.
