Abstract

The inspection methods and systems of the present invention are mobile, rapidly deployable, and capable of scanning a wide variety of receptacles cost-effectively and accurately on uneven surfaces. The present invention is directed toward a portable inspection system for generating an image representation of target objects using a radiation source, comprising a mobile vehicle, a detector array physically attached to a movable boom having a proximal end and a distal end. The proximal end is physically attached to the vehicle. The invention also comprises at least one source of radiation. The radiation source is fixedly attached to the distal end of the boom, wherein the image is generated by introducing the target objects in between the radiation source and the detector array, exposing the objects to radiation, and detecting radiation.

Claims

1. A portable inspection system for generating an image representation of target objects using a radiation source, comprising:

a mobile vehicle;

a telescopic boom support fixedly connected to said mobile vehicle, wherein said telescopic boom support is further connected to a boom arm;

a vertical detector box adjacent to said telescopic boom support;

a horizontal detector box adjacent to said boom arm;

a source arm, having a distal end and a proximal end, wherein the proximal end is connected to the boom arm and the distal end further comprises an extendable boom arm;

at least one source of radiation positioned on the extendable boom arm portion of the distal end of the source arm, wherein said image is generated by introducing the target objects in between the radiation source and the detector array, exposing said objects to radiation, and detecting radiation.

2. The portable inspection system of claim 1 wherein the telescopic boom support further comprises cylindrical portions that slide into each other, for reducing the overall height of the inspection system when in a stowed position.

3. The portable inspection system of claim 1 wherein the vertical detector box is folded on a hinge such that it is parallel to the horizontal detector box, in a stowed position.

4. The portable inspection system of claim 1 wherein the vertical detector box is folded on a hinge such that it is at an angle ranging from approximately 25°

to approximately 45°

with respect to the horizontal detector box, in a stowed position.

5. The portable inspection system of claim 1 wherein the vertical detector box further comprises an upper detector box portion and a lower detector box portion.

6. The portable inspection system of claim 5 wherein the upper detector box and lower detector box are connected by a first hinge and the upper detector box and horizontal detector box are connected by a second hinge.

7. The portable inspection system of claim 6 wherein the upper detector box and lower detector box are folded on the first hinge, in a stowed position.

8. The portable inspection system of claim 7 wherein the folded upper detector box and lower detector box are folded on a second hinge such that they are parallel to the horizontal detector box, in a stowed position.

9. The portable inspection system of claim 7 wherein the lower vertical detector box is folded on the first hinge and the upper vertical detector box is folded on the second hinge, such that they are parallel to and form a “

Z”

with the horizontal detector box, in a stowed position.

10. The portable inspection system of claim 1 wherein the source arm is folded at an angle ranging from approximately 30°

to approximately 45°

with respect to the boom arm, in a stowed position.

11. The portable inspection system of claim 1 wherein the source arm is folded at an angle of less than 30°

to the boom arm, in a stowed position.

12. The portable inspection system of claim 1 wherein the source arm is folded such that it is parallel to the boom arm, in a stowed position.

13. The portable inspection system of claim 1 wherein the overall height of the inspection system is equal to or less than nine feet in a stowed position.

19. The portable inspection system of claim 1 wherein the source arm is folded such that it is parallel to the boom arm, in a stowed position.

14. A portable inspection system for generating an image representation of target objects using a radiation source, comprising:

a mobile vehicle;

a telescopic boom support fixedly connected to said mobile vehicle, wherein the telescopic boom support further comprises cylindrical portions that slide into each other, for reducing the overall height of the inspection system and wherein said telescopic boom support is further connected to a boom arm;

a vertical detector box adjacent to said telescopic boom support;

a horizontal detector box adjacent to said boom arm;

a source arm, having a distal end and a proximal end, wherein the proximal end is connected to the boom arm and the distal end further comprises an extendable boom arm;

at least one source of radiation positioned on the extendable boom arm portion of the distal end of the source arm, wherein said image is generated by introducing the target objects in between the radiation source and the detector array, exposing said objects to radiation, and detecting radiation.

15. The portable inspection system of claim 14 wherein the vertical detector box is folded on a hinge such that it is parallel to the horizontal detector box, in a stowed position.

16. The portable inspection system of claim 14 wherein the vertical detector box is folded on a hinge such that it is at an angle ranging from approximately 25°

to approximately 45°

with respect to the horizontal detector box, in a stowed position.

17. The portable inspection system of claim 14 wherein the source arm is folded at an angle ranging from approximately 30°

to approximately 45°

with respect to the boom arm in a stowed position.

18. The portable inspection system of claim 14 wherein the source arm is folded at an angle of less than 30°

to the boom arm in a stowed position.

20. A portable inspection system for generating an image representation of target objects using a radiation source, comprising:

a mobile vehicle;

a telescopic boom support fixedly connected to said mobile vehicle, wherein said telescopic boom support is further connected to a boom arm;

a vertical detector box adjacent to said telescopic boom support;

a horizontal detector box adjacent to said boom arm;

a source arm, having a distal end and a proximal end, wherein the proximal end is connected to the boom arm and the distal end further comprises an extendable boom arm; and

at least one source of radiation positioned on the extendable boom arm portion of the distal end of the source arm, wherein said image is generated by introducing the target objects in between the radiation source and the detector array, exposing said objects to radiation, and detecting radiation and wherein said inspection system has an overall height of nine feet in a stowed position.
