title: Luggage and shipped goods.
abstract: OBJECTIVE
  Control of luggage and shipped goods are frequently carried out. The possibilities of X-ray technology shall be demonstrated.
  
  
  METHODS
  There are different imaging techniques. The main concepts are transmission imaging, backscatter imaging, computed tomography, and dual energy imaging and the combination of different methods The images come from manufacturers and personal collections.
  
  
  RESULTS
  The search concerns mainly, weapons, explosives, and drugs; furthermore animals, and stolen goods, Special problems offer the control of letters and the detection of Improvised Explosive Devices (IED).
  
  
  CONCLUSIONS
  One has to expect that controls will increase and that imaging with X-rays will have their part. Pattern recognition software will be used for analysis enforced by economy and by demand for higher efficiency - man and computer will produce more security than man alone.
