  2. What is a Body Scanner? • Security machine • Produces 3D image • Used mostly in airports • Replaces standard pat downs • More advanced security

  3. Input Component: • Backscatter X-ray beam • Substances react differently • Absorb beam, scatter beam, or let beam pass through • Electromagnetic radiation

  4. Input Component: • Millimeter Wave Scanners • Emit non-ionizing electromagnetic radiation • Similar to wireless data transmitters

  5. Input Component: • Passive Sensors • Bounce millimeter-wave or x-ray radiation off body • Obstructed waves flag foreign objects

  6. Output Component: • Image being displayed on monitor • Negative • Vivid details • Cell phone vs. gun • Virtual “strip search”

  7. Negatives • Vivid facial view • Questions about recording of images • Radiation poses health concerns • Too invasive • Scary machine

  8. Positives • Speed up security • More accurate than pat downs • Provide vivid images • Bombing attempt - 78% approved • Radiation equivalent to two minutes

  9. Conclusion • Needs to be perfected • Dependant on • Cultures/beliefs • TSA abuse
