Abstract
A proximity detector is provided for a body scanner having a scanning surface. It comprises an energy beam emitting and receiving device in front of the scanning surface of the body scanner for an energy beam projected in a plane parallel to the scanning surface. A signal generator is connected with the energy beam emitting and receiving device for generating a proximity signal when the energy beam becomes weakened or interrupted. The energy beam is preferably a light beam.
