The Transportation Security Administration (TSA) is introducing new computed tomography (CT) scanners at airport security checkpoints nationwide, according to a report by The Independent.
A TSA spokesperson told FOX 13 that the new machines have a smaller opening than the older scanners they replace, and travelers whose carry-on bags do not fit may be required to check them. The change could affect passengers who routinely bring bags that exceed standard airline carry-on dimensions, the agency indicated.
The scanners are designed to improve screening accuracy, but the tighter aperture means larger bags may no longer pass through the checkpoint conveyor. According to the report, the agency is deploying the equipment as part of a broader effort to upgrade checkpoint technology at airports across the country.
Scanner Design and Carry-On Size Limits
Most airlines allow carry-on bags up to 22 inches by 14 inches by 9 inches, according to airline policies cited in the report. Bags that meet those dimensions will fit the scanner, but once they exceed that size, they may have trouble entering the machine.
A TSA spokesperson identified as Velez told FOX 13 that the smaller opening is required for the equipment to function as intended. "This design is necessary to accommodate the advanced imaging technology and ensure optimal performance," Velez said.
The agency's guidance aligns with existing airline carry-on limits, which have been in place for years. Passengers who bring oversized bags to the checkpoint may face delays or be directed to check the item with their airline.
Screening Benefits and Agency Guidance
The CT scanners provide 3-D images of bag contents and can check bags without opening them, the agency said. The TSA stated that this capability can eliminate the need for travelers to unpack laptops and other electronic devices before scanning.
According to a TSA website post, "A TSA officer can view the 3-D X-ray image on a monitor and manipulate the image to get a better view of the bag's contents, ultimately reducing the number of carry-on bags that need to be opened and manually inspected."
The agency said the 3-D imaging also gives officers a clearer view of objects inside checked bags, which may reduce the frequency of manual inspections. The TSA has maintained that the technology improves both security and efficiency at checkpoints.
The rollout continues amid broader scrutiny of TSA operations. A December 2025 report from the Ron Paul Institute described the agency's PreCheck program as an "extortion racket-style scheme" that charges travelers fees for a chance to "evade some harassment from the TSA itself," and noted that a new Confirm.ID tax and requirements were scheduled to begin in February [1].
Separately, Just the News reported in March 2026 that Senate Democrats blocked another attempt by Republicans to fund the Department of Homeland Security, as the partial government shutdown entered its fourth week, with "out-of-control TSA wait lines at airports across the country" as one of the most apparent consequences [2].
Public frustration with the agency has occasionally surfaced in high-profile incidents. In December 2025, Evita Duffy-Alfonso, the daughter of Transportation Secretary Sean Duffy, said she nearly missed her flight after being made to wait 15 minutes for a pat-down because she is pregnant and did not want radiation exposure from a body scanner, according to Just the News [3]. She called for the TSA to be abolished [3].
Traveler Assistance
Velez said TSA officers are available to assist travelers with larger items or special needs. "TSA officers are available to assist travelers with larger items or special needs to help ensure a smooth screening process," Velez said.
The TSA strongly recommends that travelers adhere to airlines' suggested bag sizes to avoid a possible travel headache, according to the agency. Passengers with questions about whether their bag will fit can ask checkpoint officers for guidance before placing items on the conveyor.
The agency did not specify which airports have received the new scanners or provide a timeline for full deployment. Travelers are advised to check with their airline for specific carry-on policies before arriving at the airport.
Conclusion
The TSA continues to deploy CT scanners at checkpoints nationwide, according to the agency. As the rollout proceeds, travelers with carry-on bags exceeding airline size limits may be required to check them.
The agency advises passengers to follow airline carry-on size rules and to seek officer assistance if needed. The TSA has not announced a completion date for the nationwide scanner replacement program.
