I went through Schiphol this afternoon & one of their new security gates - a backscatter X ray scanner to detect hidden weapons and explosives on passengers. These devices, which use Compton scattering that require that the passenger stand close to a panel and produce a high resolution image.
It seems to slow the process down you have to stand at 90 degrees to the entry point and raise your arms. The scamnner rotates inside a cylindrical perspex section that forms the side of the machine
The image is of Susan Hallowell, Director of the US Transportation Security Administration's research lab, taken with backscatter X-ray system, used for airport security passenger screening. hattip Wikipedia and the Boston Globe
