Appl. No.:

10/071147

Inventors:

David E. Kresse - Walnut Creek CA

Assignee:

InVision Technologies, Inc. - Newark CA

International Classification:

B22D 708

US Classification:

164113, 164312

Abstract:

According to one embodiment of the invention, a method of making a collimator for a detector array of an x-ray technique-based nonintrusive inspection apparatus is provided. The method includes injecting a die with a material, the die being shaped and dimensioned to form a collimator including a body defining a support structure and a plurality of septa secured to the support structure; allowing the material to set within the die to form the body; and removing the body from the die.

Inventors:

Andrew J. Banchieri - Newark CA, US
David E. Kresse - Walnut Creek CA, US

Assignee:

InVision Technologies, Inc. - Newark CA

International Classification:

G01N023/04

US Classification:

378 57, 378196, 378203

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.

Inventors:

David E. Kresse - Walnut Creek CA, US
Andrew J. Banchieri - Newark CA, US

Assignee:

InVision Technologies, Inc. - Newark CA

International Classification:

G01N023/00

US Classification:

378 19, 378 4, 378151

Abstract:

An x-ray-based nonintrusive inspection apparatus has a collimator shield. An adjusting actuator is actuable to move the collimator shield between a pre-scanning position and a CT scanning position, in the pre-scanning position, the collimator shield exposing a smaller portion of a respective crystal to the x-rays than in the CT scanning position. A controller is connected to a gantry motor and the adjusting actuator. The controller controls the motor and the adjusting actuator such that the collimator shield is in the pre-scanning position when a gantry is stationary and in the CT scanning position when the gantry is rotating.
