Abstract: A system for reconstructing an image of an object includes a mobile imaging system, and a user removable module configured to be attached to the mobile imaging system.

Abstract: The present invention provides for an x-ray system and method using dynamic automated spatial modulation of an x-ray beam. The system includes an x-ray source transmitting a spatially modulated beam towards an object to be imaged, an x-ray detector receiving the beam and measuring a plurality of intensities across the beam, a beam processor controlling the beam intensity profile, and an image processor producing an output image signal. The detector produces a residual image based on at least the intensities measured at the detector. The beam intensity profile may be based on at least some of the following: (a) the residual image from the x-ray detector, (b) current beam intensities, (c) regions on interest in the image, and (d) predicted or measured object motion in the image. The system's output image is based on one or more of said residual image and said beam intensity signal.
