Abstract

A crane including support means arranged to support a load and to move the load along a path, and a scanner including a radiation source and radiation detection means arranged to scan a scanning volume. The path is arranged to pass through the scanning volume so that the scanner can scan the load as it moves along the path.

First claim

I claim:

1. A scanning system for scanning a load suspended from a crane by a suspension system comprising:
a scanning system support frame defining a partially enclosed scanning volume, wherein the scanning system support frame is attached to a portion of said crane;
a gap at a top of said scanning system support frame;
an X-ray source angularly positioned at a base of said scanning system support frame; and
detectors positioned diagonally opposite said X-ray source, wherein the X-ray source and detectors are adapted to scan the load and generate scan data as the suspension system moves the load through said gap and into said scanning volume.

2. The scanning system of claim 1 wherein said scanning system support frame is attached to a frame of said crane.

3. The scanning system of claim 1 further comprising wheels, wherein the frame of said crane is positioned atop, and supported by, the wheels.

4. The scanning system of claim 1 further comprising at least one radiation detector positioned outside the scanning volume for detecting radiation escaping from the scanning volume.

5. The scanning system of claim 1 wherein the scanning system support frame is rectangular.

6. The scanning system of claim 1 wherein the detectors are positioned within a top portion and a side portion of the scanning system support frame.

7. The scanning system of claim 1 further comprising a support structure projecting horizontally from a top end of a portion of the crane and a rail extending horizontally along a length of the support structure, wherein a portion of the crane is adapted to be movable along said rail.

8. The scanning system of claim 1 further comprising a communication system for wirelessly transmitting the scan data corresponding to each scanned load to a remote station.

9. The scanning system of claim 1 further comprising a load monitoring system for detecting the load entering the scanning volume and transmitting an activation signal.

10. The scanning system of claim 9 further comprising a control system for receiving said activation signal and activating the X-ray source based upon said activation signal.

11. The scanning system of claim 10 wherein the load monitoring system comprises at least one of an infrared sensor and a video camera.

12. The scanning system of claim 1 further comprising a load monitoring system for detecting the load leaving the scanning volume and transmitting a de-activation signal.

13. The scanning system of claim 12 further comprising a control system for receiving said de-activation signal and de-activating the X-ray source based upon said de-activation signal.

14. The scanning system of claim 1 further comprising an identification system, wherein the identification system comprises at least one of a camera, a video camera and a bar code scanner and wherein the identification system is adapted to identify the load by determining one or more of an identification number and a barcode.

15. The scanning system of claim 1 further comprising an identification system adapted to generate identity information, wherein the identification system comprises at least one of a camera, a video camera and a bar code scanner and wherein the identification system is adapted to associate the identity information with the scan data.

16. A method for scanning a load comprising:
vertically suspending the load from a suspension system, wherein the suspension system is attached to a crane;
using the crane and suspension system, horizontally moving the vertically suspended load through a gap positioned at a top of a scanning system support frame, wherein the scanning system support frame defines a partially enclosed scanning volume, wherein an X-ray source is angularly positioned at a base of said scanning system support frame, and wherein detectors are positioned diagonally opposite said X-ray source; and
using the X-ray source and detectors, scanning the load and generating scan data as the suspension system moves the load through said gap.

17. The method of claim 16 further comprising detecting radiation escaping from the scanning volume using at least one radiation detector positioned outside the scanning volume.

18. The method of claim 16 further comprising monitoring whether the load is entering or leaving the scanning volume using a load monitoring system.

19. The method of claim 18 further comprising activating the X-ray source when the load is detected as entering the scanning volume.

20. The method of claim 16 further comprising generating identity information and associating identity information with the scan data using an identification system, wherein the identification system comprises at least one of a camera, a video camera and a bar code scanner.
