The TSA new 3D bag scanners are being introduced with a smaller opening than older scanners. Travelers whose carry-on bags exceed airline size limits may have to check them before screening.
The machines show TSA officers a three-dimensional image of everything inside a bag and can reduce the need to open carry-ons by hand. A TSA spokesperson, Velez, said, “This design is necessary to accommodate the advanced imaging technology and ensure optimal performance.”

Velez told 13 that the smaller opening is necessary for the machine to work correctly. TSA officers are available to help travelers with larger items or special needs, and the agency strongly recommends staying within airline carry-on limits.
Most airlines allow carry-on bags up to 22 inches by 14 inches by 9 inches. Bags that fit those limits should fit the scanner, while bags that run larger may have trouble entering the machine. The scanners can also spare travelers from unpacking laptops and other electronic devices before screening.
What TSA officers can see
Inside the checkpoint, a TSA officer can view the 3-D X-ray image on a monitor and manipulate it to get a better look at the bag’s contents. That screening method is meant to catch enough detail without requiring as many bags to be opened and searched manually.
For travelers, the practical move is simple: pack to the airline size standard before arriving at the checkpoint. If a carry-on is oversized, the bag may need to be checked before it reaches the scanner, and travelers with larger items can ask TSA officers for help during screening.
