Abstract

A nonintrusive inspection apparatus is described of the kind having a base frame, an elongated shield on the base frame, a conveyor belt passing through the shield which is used for transporting closed containers, and a rotating CT scanner subsystem which is used for scanning the container on the conveyor belt. The CT scanner subsystem is mounted through the shield to the base frame. The shield provides sufficient rigidity for the CT scanner subsystem. A cover is positioned over the CT scanner subsystem, but only over a portion of the shield, thereby allowing for a person on one side of the shield to see a person on an opposite side of the shield.

Claims (11)

1. A nonintrusive inspection apparatus, comprising:

a base frame;

an elongated first shield mounted to the base frame and defining a tunnel through which a container can pass;

a gantry rotatably mounted to the base frame;

an x-ray source mounted to the gantry; and

a cover located over the x-ray source, the gantry and a portion only of the first shield.

2. The system of claim 1 , wherein the gantry is mounted through the first shield to the base frame.

3. The system of claim 1 , wherein the cover is located over less than 50% of the first shield.

4. The system of claim 1 , further comprising:

an elongated second shield mounted to the base frame on a side of the gantry opposing the first shield, the cover being located over a portion only of the second shield.

5. The system of claim 4 , wherein the cover includes left and right portions, at least one of which is movable relative to the other to expose the gantry.
