TSA spokesman Dwayne Baird says the pictures online right now are of models demonstrating how the equipment works. He is quick to say the equipment cannot save, print or send images of passengers.
"Once we resolve the image, then the next passenger comes into the machine and the image that is on the screen is immediately deleted," Baird said.
He says the scanners are part of a pilot program right now at several airports around the nation.
TSA says that some people are bringing items through the checkpoint that are not allowed. When the prohibited items are not metallic, they would not be picked up with the walk-through metal detector.
The screeners are in a resolution room away from the checkpoint, so they don't see the face or identity of the person being screened. That way even celebrities coming through won't be identified and potentially exploited.
