1. A computed tomography system for multi-target inspection comprising: an X-ray source; a multi-target positioning unit having multiple target supports, each of the multiple target supports being located along a corresponding line of sight of the X-ray source of the system, the multiple target supports being operative to orient multiple targets simultaneously such that each of the multiple targets is positionable at multiple orientations; wherein the multi-target positioning unit has a carrier operative to support the multiple target supports and to move the multiple target supports vertically relative to the X-ray source; and wherein the multiple target supports are operable to move laterally relative to the carrier; wherein each of the multiple target supports is rotatable to rotate a target; and wherein the multi-target positioning unit has a drive motor and a following mechanism, the drive motor being operative to drive a first of the multiple target supports, the following mechanism being driven by the first of the multiple target supports and being operative to drive a second of the multiple target supports.
