An image scanning system including a plurality of spatially-distributed radiation beam sources, each source operative to emit a radiation beam characterized by a distinguishing parameter unique to each radiation beam source, and a common detector arranged with respect to the radiation beam sources such that the radiation beam sources emit their radiation beams onto the common detector which is operable to receive and distinguish the radiation beams on the basis of their respective distinguishing parameters so as to acquire partial projections sets of an object through which the radiation beams pass, wherein a union of the partial projections sets forms a projection set sufficient for reconstruction of an image of the object.
