Patent ID: 7016459

Claim:
A computed tomography (CT) scanner for scanning an object, the CT scanner comprising: a tunnel; a conveyor for moving the object through the tunnel; a gantry movable relative to the tunnel; an x-ray source for providing an x-ray beam that intersects the tunnel; a first set of detectors on the gantry, the detectors in the first set all being positioned substantially at a same first distance from the x-ray source, the first set of detectors being positioned opposite the x-ray source so that the gantry has first and second sections extending on opposite sides of the gantry between the x-ray source and the first set of detectors; and a second set of detectors positioned on the first section of the gantry, the detectors in the second set all being positioned substantially at a same second distance from the x-ray source, the second distance being less than the first distance.
