American Science and Engineering, which is another manufacturer of the backscatter X-ray machines, has sold 500 backscatter machines that run in a van, on the highway, and can be used to scan neighboring vehicles as they drive by.
These machines do not only scan the shape of an object, detection circuitry can also detect certain compositions, such as explosives, drugs, etc.
