Patent ID: 8098794

Claim:
An x-ray imaging system for a moving article, comprising: a conveyor device for moving an article adapted to be placed thereon along a linear direction of travel; a first x-ray source for directing a first x-ray beam towards said conveyor device wherein said first x-ray beam passes through the article moving along said conveyor device; a second x-ray source for directing a second x-ray beam towards said conveyor device wherein said second x-ray beam passes through the article moving along said conveyor device, said first x-ray beam and said second x-ray beam being non-overlapping; a first sensor arrangement disposed in said first x-ray beam passed through the article moving along said conveyor device, said first sensor arrangement defined by at least two parallel linear sensor arrays oriented perpendicular to said linear direction of travel of said conveyor device and spaced apart from one another along said linear direction of travel; a second sensor arrangement disposed in said second x-ray beam passed through the article moving along said conveyor device, said second sensor arrangement defined by at least two parallel linear sensor arrays oriented perpendicular to said linear direction of travel of said conveyor device and spaced apart from one another along said linear direction of travel, wherein relative spacing between said arrays associated with said first sensor arrangement is identical to relative spacing between said arrays associated with said second sensor arrangement; and a processor for merging image data collected by each of said arrays associated with said first sensor arrangement with a unique one of said arrays associated with said second sensor arrangement based on one-to-one correspondence between said relative spacing associated with said first sensor arrangement and said second sensor arrangement.
