TSA tests scanners that will allow travelers to keep electronics and liquids in their bags when going through airport security.

Frequent airport travelers know the drill. Remove all electronics and liquids from carry-on bags and place them in a tray. But at more than a dozen airports, passengers are now being told to keep their items in their luggage.

This summer, Transportation Security Administration is testing its Computed Tomography (CT) scanners at 15 airports across the country. Phoenix Sky Harbor International Airport was the first facility to receive the advanced screening innovation in 2017, followed by Boston Logan and New York's JFK.

TSA spokesperson Michael McCarthy says the scanners will be at O'Hare International Airport before the end of the year.

The 3-D imaging equipment resembles a hospital CT scanner using X-ray scanning equipment to enhance threat detection capabilities for carry-on baggage.

TSA's current screening technology uses 2-D images. The new technology applies sophisticated algorithms that the agency believes will more easily detect explosives and other threats. Screeners will view a 3-D image that can be viewed and rotated 360 degrees for a thorough analysis.

The initial CT units are being deployed to the following airports:

Baltimore-Washington International Airport (BWI)
Chicago O'Hare International Airport (ORD)
Cincinnati/Northern Kentucky International Airport (CVG)

Houston Hobby Airport (HOU)
Indianapolis International Airport (IND)
John F. Kennedy International Airport (JFK)
Logan International Airport (BOS)
Los Angeles International Airport (LAX)
McCarran International Airport (LAS)

Oakland International Airport (OAK)
Philadelphia International Airport (PHL)
Phoenix Sky Harbor International Airport (PHX)
San Diego International Airport (SAN)
St. Louis Lambert International Airport (STL)
Washington-Dulles International Airport (IAD)

TSA plans to have 15 units in place at airports around the nation within the next few months.
