1. A multi-mode imaging apparatus comprising:

  • an X-ray source operable in at least a mammography mode and a tomosynthesis mode;

    a detector;

    an anti-scatter grid positioned between the X-ray source and the detector, wherein the anti-scatter grid comprises a plurality of septa wherein at least one septa of the plurality of septa extends substantially parallel to a coronal plane of a subject during imaging by the X-ray source; and

    a motor coupled to the anti-scatter grid and configured to selectively move the anti-scatter grid, wherein the anti-scatter grid is retracted out of a field of view of the X-ray source in the mammography mode, wherein the anti-scatter grid is configured to move at least partially within a field of view of the X-ray source in the tomosynthesis mode, and wherein during imaging by the X-ray source in the tomosynthesis mode, the anti-scatter grid is movable in a direction wherein the at least one septa maintains substantially parallel orientation to the coronal plane of the subject.
