An x-ray scanning system including an x-ray source defining a focal spot (9) from which radiation is emitted, an x-ray detector assembly (14) including a plurality of x-ray detectors (24) cooperative with the x-ray source to define a radiation beam extending from the focal spot to all of the detectors, a support for supporting at least one of the x-ray source and the detector assembly for rotation about an isocenter (16), and means for configuring the detectors so that the increment in radial distance from the isocenter to the centers of any two adjacent subbeams is a substantially constant value. |
