People haven’t complained much in the week since the Transportation Security Administration replaced two full-body scanners at the Boise Airport with new machines that don’t produce images of the person being scanned, spokeswoman Patti Miller said.

In fact, Miller said, it’s been hard to tell if passengers have noticed the swap.

“They haven’t commented at all,” she said. “We have had almost no response.”

A month ago, the TSA announced that security screening provider Rapiscan Systems failed to integrate congressionally mandated security software in its body scanners - the same scanners that some passengers complained show revealing images of the people being scanned. TSA terminated Rapiscan's contract, and the company must remove its scanners at its own cost, according to a TSA news release.

The new machines, known as L3 Millimeter Wave body scanners, show only an abstract human form, instead of the more true-to-life body image the Rapiscan equipment produced.
