1. System for performing digital tomosynthesis on an object region, comprising:

  • a stationary x-ray detector for detecting x-ray radiation transmitted through the object region and for producing image data representative of the intensity of the radiation;

    a moveable x-ray source for generating the x-ray radiation;

    a motion controller for moving the x-ray source to a plurality of positions defining an arc about the region; and

    a data processor for determining x-ray absorption points within the region based upon an image data set having image data corresponding to each of the positions.
