Since the terrorism attack happened on September 11th 2001, many countries have realized the significance of this serious security issue, and they have begun to crack down on terrorism, and are actively participating in anti-terrorism cooperation for strengthening national security. Scientists have developed technology and research into high performance safeguards. Some fundamental safety equipment is used at the airports for checking out hazardous materials among the passengers. The full body scanner is a typical example being used at airports for safety inspections, and it shows the newest airport security technology.

In light of these complex working principles, both use about 10 minutes to finish a complete individual scanning (Stanton, 2010), and the average velocity of the scanning is higher than a hand-held scanner; however, by using the millimeter-waves, the images come up clearer and faster (Cavoukian, 2009). Moreover, both not only detect the metallic materials but also plastic, chemical or other hazardous materials, carried by the human body (Tessler, 2009). In contrast, the regular physical scan can only catch the metallic items; therefore, people can easily understand these multiple superior technical aspacts to support the full body scanner protecting the safety of passengers and preventing serious crimes.
