While the purpose of the scanners is to find contraband hidden on the body, some weapons and explosives would not be visible to the devices say the researchers, who are known for their work in creating magnetic resonance imaging (MRI) machines used in hospitals.
That's because the human body and benign objects add "structured noise that interferes with signal averaging," the scientists say.
A "pancake" of explosives with beveled edges, taped to the abdomen, for instance, "would be invisible to this technology, ironically, because of its large volume, since it is easily confused with normal anatomy," the scientists report.
"It is also easy to see that an object such as a wire or a boxcutter blade, taped to the side of the body, or even a small gun in the same location, will be invisible," Kaufman and Carlson write.
Increasing radiation exposure to get a better image from the body scanning technology won't help, the scientists say. "Even if exposure were to be increased significantly, normal anatomy would make a dangerous amount of plastic explosive with tapered edges difficult if not impossible to detect."
So, while the average citizen will be sacrificing rights for security supposedly at the airports, remember this Barf Stew link.
