ABSTRACT:
A high speed computed tomography x-ray scanner using a plurality of x-ray generators. Each x-ray generator is scanned along a source path that is a segment of the scanner's source path such that each point in the source path is scanned by at least one tube. X-ray generators and detectors can be arranged in different scan planes depending on the available hardware so that a complete and near planar scan of a moving object can be assembled and reconstructed into an image of the object.
