Array CT
First Claim
1. An x-ray scanning system, comprising:
- a conveyor disposed at least partially in a tunnel and configured to move an object to be scanned through the tunnel along a direction of travel;
a first x-ray source disposed beneath the tunnel and configured to project a plurality of fan beams from a first focal point through the tunnel;
a first plurality of detector arrays, wherein each of the detector arrays is aligned to one of the fan beams projected from the first x-ray source;
a second x-ray source disposed on the side of the tunnel and configured to project a fan beam from second focal point through the tunnel; and
a second detector array aligned to the fan beam projected from the second x-ray source.

Abstract
Embodiments of an Array CT scanning system for x-ray scanning objects (e.g., scanning airline baggage, packages, and cargo) can include a conveyor configured to transport baggage through a tunnel, a bottom mounted x-ray source configured to provide five fan beams through the tunnel, a side mounted x-ray source disposed at a height higher than the conveyor and configured to provide a fan beam through the tunnel, and a plurality of detectors disposed across the arcs of each of the fan beams. An image processing system can be configured to provide 3D type images of a scanned bag as a function of the information received from the detectors. The images can be derived through interpolation of the scan data. An operator can manipulate the image data and partially rotate the bag to discern objects located within. A side tray is provided to allow an operator to remove a suspect bag from an operational flow of bags. Image information can be stored for subsequent review. Multiple scanners can be networked together such that image and passenger information can be transferred to other workstations.

10. An array CT scanning system, comprising:
-
a tunnel; a conveyor disposed at least partially within the tunnel can configured to move an object to be scanned through the tunnel along a direction of travel; a single detector array disposed in proximity to the tunnel; a plurality of x-ray sources disposed on the tunnel along the direction of travel, wherein each x-ray source is configured to project a fan beam towards the single detector; and a control system operably coupled to the x-ray sources and configured to activate each of the x-ray sources sequentially such that only one x-ray source is projecting at a time. - View Dependent Claims (11, 12, 13, 14, 15)
