Patent ID: 8586955

Claim:
An apparatus for attenuating high energy radiation during vehicle inspection, the apparatus comprising: a plurality of attenuation members for attenuating high energy radiation in a corresponding plurality of portions of a high energy radiation field emitted from a high energy radiation source towards a subject vehicle; and a control unit for determining the corresponding plurality of portions of the high energy radiation field to be attenuated by the plurality of attenuation members based on comparison between the type of the vehicle as identified from an image of the vehicle and predefined criteria for the type of the vehicle defined prior to activation of one or more of the plurality of attenuation members, and for selectively activating the one or more of the plurality of attenuation members to attenuate the determined corresponding plurality of portion of the high energy radiation field; wherein the predefined criteria corresponds to typical driver and passenger locations in the type of the vehicle and the attenuating of the high energy radiation in the determined corresponding plurality of portions shields each of the typical driver and passenger locations separately.
