I'm pretty sure that even if they couldn't get the actual images out of the machine, they can easily take a picture of the image with their mobile cameras.
Couldn't the TSA agent viewing these images take a picture with their smartphone? That's just off the top of my head.
I'm more curious about any research into health effects of millimeter wave scans? My business partner always opts out claiming this but could never provide evidence.
I haven't heard of any conclusive evidence that it doesn't harm either (and how could there be one, since they haven't been used for that long), but why take the risk in the first place
