A computed tomography scanner includes a housing, a conveyor disposed at least partially within the housing and configured to move an object to be scanned through the housing along a direction of travel, a gantry connected to the housing and configured to receive the object to be scanned, an x-ray source attached to the gantry and configured to provide an x-ray beam that extends along a length in the direction of travel, and detector arrays attached to the gantry and configured and disposed to receive and detect x-rays from the x-ray source, the detector arrays being displaced relative to each other in the direction of travel an array spacing distance such that a geometric efficiency of the arrays is less than about 80%. |
