Personnel screening system

摘要

The present specification discloses an inspection system for detecting objects being carried by a person who is moving along a pathway. The inspection system has two detection systems configured to detect radiation scattered from the person as the person moves along the pathway and an X-ray source positioned between the detection systems. The X-ray source is configured to generate a vertical beam spot pattern and does not generate beams that move horizontally.

1. An inspection system for detecting objects being carried by a person, the inspection system comprising:
an X-ray source configured to generate a beam spot pattern of radiation that moves in a direction perpendicular to a direction of motion of the person; a first detection system and a second detection system both configured to detect radiation scattered from said person; wherein said X-ray source is coupled with a beam chopper to produce a scanning pencil beam of X-rays, wherein said beam chopper comprises a chopper wheel having three slits, and wherein each slit is positioned 120 degrees apart from an adjacent slit; and wherein said X-ray source generates a beam spot pattern by pivoting from a first point to a second point and wherein said pivoting is centered around a predefined point of rotation.
