Rapiscan Systems' Rapiscan WaveScan 200

Designed for screening people, the WaveScan 200 uses a full-motion video camera and so-called millimeter wave technology, which beams radiation over a body's surface, to detect potentially harmful objects carried close to the body. To protect privacy, the WaveScan 200 doesn't capture images of anatomical details. Available since 2004, the system costs $100,000 and is used by customs agents around the world.
