Abstract

The present application is a self-contained mobile inspection system and method and, more specifically, improved methods and systems for detecting materials concealed within a wide variety of receptacles and/or cargo containers. In particular, the present application is an improved method and system for inspecting receptacles and/or cargo containers using a single boom placed on a turntable with pivot points to allow for folding and unfolding of the boom, such that the inspection system is relatively compact in a stowed configuration and has a low center of gravity lending to greater stability.

Claims

1. A foldable boom structure for use in a cargo inspection system wherein said foldable boom structure comprises a stowed configuration and an operational configuration:

a. wherein the stowed configuration comprises

a first section, having a first end and a second end, wherein said first section is in a first plane and is pivotally coupled, at the first end, to a back surface of a vehicle and wherein said first plane is substantially parallel to a plane defined by the back surface of the vehicle;

a second section having a first end and a second end, wherein said second section is substantially parallel to the first section, and wherein the first end of the second section is pivotally connected to the second end of the first section; and

a third section having a first end and a second end, wherein said third section is substantially parallel to the first section and the second section, and wherein the first end of the third section is pivotally connected to the second end of the second section; and

b. wherein the operational configuration comprises

said first section, in a second plane, wherein said second plane is substantially perpendicular to the plane defined by the back surface of the vehicle;

said second section, wherein said second section is substantially perpendicular to the first section and wherein the first end of the second section is pivotally connected to the second end of the first section; and

said third section, wherein said third section is substantially parallel to the first section and perpendicular to the second section and wherein the first end of the third section is pivotally connected to the second end of the second section.

2. The foldable boom structure of claim 1 further comprising a first detector array housing physically attached to the second section, wherein said first detector array housing contains a plurality of detectors.

3. The foldable boom structure of claim 2 further comprising a second detector array housing physically attached to the third section, wherein the second detector array housing contains a plurality of detectors.

4. The foldable boom structure of claim 3 wherein, in the operational configuration, said first detector array and said second detector array are arranged to receive transmitted radiation from at least one radiation source.

5. The foldable boom structure of claim 4 wherein the radiation source comprises at least one gamma ray source.

6. The foldable boom structure of claim 5 wherein the at least one gamma ray source is ⁶⁰Co or ¹³⁷Cs.

7. The foldable boom structure of claim 1 wherein said foldable boom structure is adapted to be positioned to form a scan angle position relative to the vehicle and wherein the scan angle position ranges between 80°

and 100°

.

8. A foldable boom structure for use in a cargo inspection system wherein said foldable boom structure comprises a stowed configuration and an operational configuration:

a. wherein the stowed configuration comprises

a first linear member, having a first end and a second end, wherein said first section is substantially horizontal and is coupled, at the first end, to a back surface of a vehicle;

a second linear member having a first end and a second end, wherein said second linear member is substantially horizontal, and wherein the first end of the second linear member is pivotally connected to the second end of the first linear member; and

a third linear member having a first end and a second end, wherein said third linear member is substantially horizontal, and wherein the first end of the third linear member is pivotally connected to the second end of the second linear member; and

b. wherein the operational configuration comprises

said first linear member, wherein said first linear member is substantially vertical, wherein the second end is elevated relative to the first end, and wherein the first end is coupled to the back surface of a vehicle;

said second linear member, wherein said second linear member is substantially horizontal, wherein said second linear member is perpendicular to the first linear member, and wherein the first end of the second linear member is pivotally connected to the second end of the first linear member; and

said third linear member, wherein said third linear member is substantially parallel to the first linear member and perpendicular to the second linear member and wherein the first end of the third linear member is pivotally connected to the second end of the second linear member.

9. The foldable boom structure of claim 8 further comprising a detector array housing physically attached to the second linear member, wherein said detector array housing contains a plurality of detectors.

10. The foldable boom structure of claim 9 wherein, in the operational configuration, said plurality of detectors is arranged to receive transmitted radiation from at least one radiation source.

11. The foldable boom structure of claim 10 wherein the radiation source comprises at least one gamma ray source.

12. The foldable boom structure of claim 11 wherein the at least one gamma ray source is ⁶⁰Co or ¹³⁷Cs.

13. The foldable boom structure of claim 8 further comprising a detector array housing physically attached to the third linear member, wherein the detector array housing contains a plurality of detectors.

14. The foldable boom structure of claim 13 wherein, in the operational configuration, said plurality of detectors is arranged to receive transmitted radiation from at least one radiation source.

15. The foldable boom structure of claim 14 wherein the radiation source comprises at least one gamma ray source.

16. The foldable boom structure of claim 15 wherein the at least one gamma ray source is ⁶⁰Co or ¹³⁷CS.

17. The foldable boom structure of claim 8 wherein said foldable boom structure is adapted to be positioned to form a scan angle position relative to the vehicle and wherein the scan angle position ranges between 80°

and 100°

.

18. The foldable boom structure of claim 8 further comprising a first detector array housing physically attached to the second section, wherein said first detector array housing contains a plurality of detectors.

19. The foldable boom structure of claim 18 further comprising a second detector array housing physically attached to the third section, wherein the second detector array housing contains a plurality of detectors.

20. The foldable boom structure of claim 19 wherein, in the operational configuration, at least one of said first detector array or said second detector array are arranged to receive transmitted radiation from at least one radiation source.
