The Transportation Security Administration (TSA) is expanding the use of computed tomography (CT) scanners at airport checkpoints. These advanced devices offer a 3D image of items inside carry-on bags. In contrast, older X-ray machines only produced 2D images. With CT technology, travelers may not need to remove items from their bags for scanning.

A traveler moves through the TSA line at Washington Dulles International Airport. The shift to CT scanners suggests an improvement in detecting potential threats that older systems might have missed. This transition, though beneficial for security, has faced criticism. Some argue that subjecting all carry-on bags to CT scanning could be a misguided approach.

The Hill, a nonpartisan source, reports on the implications of government actions and their intersection with business and politics. In this instance, deploying CT technology in airports is seen as a significant development within security protocols.
