A CT scanning system including a gantry operable to rotate about a rotation axis, and a plurality of X-ray imagers mounted on the gantry, each X-ray imager including a radiation source and a detector, wherein the radiation source is operative to emit a radiation beam (e.g., a cone beam) and the detector is positioned to receive the radiation beam so as to acquire partial projections set of an object through which the beams pass, wherein a union of the partial projections sets forms a projection set sufficient for CT reconstruction of the object.
