Provided are CT scanning systems and architectures that utilize a unique approach to scanning large objects. Various embodiments of the architecture incorporate a scanning platform and a turntable. The scanning platform may be mounted horizontally. The vertical offset between the scanning platform and the turntable may be changed during a scan. A pallet or other object can be moved into a scanning area under the scanning platform. Both the vertical offset between the scanning platform and the turntable may be changed and the turntable may be rotated during a scan. Scan data may be used to generate a three dimensional image. Additional objects can be quickly positioned (once the vertical offset is adjusted) for subsequent scans allowing for greater throughput than conventional approaches.
