1. A system to provide fast 3D radiography, comprising:
a primary motor stage moving along a direction of an arc rail at a speed;
a primary motor that engages with said primary motor stage;
a plurality of secondary motor stages coupled to said primary motor stage and move along a direction of the arc rail, wherein a plurality of secondary motors move the plurality of secondary motor stages in an opposite direction to the primary motor stage;
a plurality of X-ray sources coupled to and moved by one of the plurality of secondary motor stages; and
a flat panel detector to receive X-ray imaging data, wherein the plurality of X-ray sources and flat panel detector are triggered when one of the plurality of the secondary motor stages travels in the opposite direction to the primary motor stage, wherein the primary motor controls the speed of the primary motor stage and wherein the secondary motors control a speed of the secondary motor stages.
