Overlay a thin layer of material over the metal plate (the dark/black region in the images) that has a regular repeating pattern (think checkerboard) that shows objects suspended beyond the body's silhouette.
Problem solved.
- xymostech 15y agoBut that would probably ruin the scan from the other direction? There are two pictures, I thought because there is a scan from the front and a scan from the back.
- ams6110 15y agoSo it sounds like the easy solution is to do two scans. One face-on, and then they ask you to turn to the side and they do another.

- burgerbrain 15y agoOr inner arm for that matter. Also, does anybody know what prevents people from simply taping a knife to the bottom of their foot, under their sock?

- teej 15y agoThe problem isn't that this one particular technique exists. The problem is that the TSA's decision making process led them to spend billions of dollars a year against the advisement of the top security experts in the world. For an organization who's sole purpose is the security of the American people, they're awfully bad at doing things that ensure the security of the American people.
- ams6110 15y agoA big problem with that procurement was the very close ties between former TSA director, Michael Chertoff, and the company that makes the full body scanners.
- shareme 15y agono they are spending billions to advertise traveling securely as what they are attempting to secure is so statistically approaching zero to be laughable.. in the 1970s when it was found that people could highjack planes by delivery a threatening note or bomb and using a parachute to jump out with money what do you think the airlines did?\ They took the statistically significant thing and changed how planes were designed to prevent people being able to jump out of airliners through the back escape doors. It did not cost billions of dollars and no extra xray scanning machines were used either.. First act of de-toothing TSA is putting those qualified on security of airlines..the airlines themselves back in charge of security!'
- rorrr 15y ago> For an organization who's sole purpose is the security of the American people Their sole purpose is to make money. They obviously don't give a damn about security.
- einhverfr 15y agoHow many places do you think assume security is a problem that can be solved by buying fancy products? This is an all-too-common mistake. I am sure we have all seen it in the IT industry. I am surprised we don't just recognize it and call it out as such when we see the federal government doing the same.

- aroberge 15y agoWhy do you think it is black in the first place? Think physics and X-rays, not computer screen...
- akavi 15y agoHave the backgroundpattern made of alternating pieces of absorbent and transparent material, then. (I assume the machines work by measuring obstruction of rays. If they work by reflection of rays, then replace "absorbent and transparent" with "absorbent and reflective".)
- bpd1069 15y agoYes, that is basically what I suggested, the material (film) would just drape over the backscatter plate. The resultant image (without a subject) would resemble a black / not so black checkerboard pattern. The image appears to be a negative relative to the amount of xrays reflected back to the xray source so the additional material would simply have to be slightly less reflective (more absorbent) than the backscatter plate.
- ktizo 15y agoNo, the image is the positive of the reflected xray, white is more backscatter. Metal has little backscatter and neither does empty space. There is no 'backscatter plate' in terms of a background required to generate the silhouette as far as I am aware.
- samstave 15y agoIsn't it solved by just forcing the scanee to turn to the side, scan front rear and sides? Great - now the time to get through security just went up! I mean, the TSA idiots STILL require us to remove our shoes because of some joker with a lighter attempting to burn his foot.
