1. An X-ray inspection system with variable energy dose rate for screening vehicles, the X-ray inspection system comprising:

  • an X-ray source for generating an X-ray beam, having an intensity level, to create a scanning region;

    at least one detector array to receive X-ray beam signals transmitted through a vehicle; and

    a collimator that modulates the intensity level of the X-ray beam to produce a low X-ray energy dose rate or a high X-ray energy dose rate depending upon a portion of the vehicle being screened, wherein the collimator varies the intensity level of the X-ray beam such that a portion of the vehicle carrying people receives the low X-ray energy dose rate and a portion of the vehicle carrying cargo receives the high X-ray energy dose rate.
