Technology

Small amounts of radio signals are projected over the surface of the body at high speed. This is done using two antennas as they rotate around the body. This energy is then reflected back from your body and any other objects within its beam. This reflection is then used to construct a 3-dimensional image. This image of the body is displayed on a remote montior for analysis.

According to the TSA, there is no way to save, print or transfer the image once it’s shown on the screen.
