The TSA doesn&#x27;t use backscatter x-ray machines any more. They were all removed because the company that makes them (Rapiscan) couldn&#x27;t figure out a way to mask the naked images.<p>Now they just use millimeter wave machines, which have the body outlines only. I really don&#x27;t find this objectionable from a privacy standpoint. It it basically a better metal detector in that it detects non-metal objects, too, and shows the scanner exactly where they are on the body.
