> Does the scanner not pick the object up at all (I don't see why this would be true)

The object and the background both look the same in reflected x-rays. It's not just the background color.

In that case, couldn't they put a non-reflective material behind the person being scanned?

Perhaps that would interfere with their ability to scan you from both sides, but if they have a reflective material behind you it seems like they must already have a way to scan through/around that.
