Abstract: A mobile X-ray system for digital tomography is disclosed. The mobile X-ray system comprising a multiple degree of freedom robotic arm comprising one or more extendable arms and a column member; an X-ray source mounted on an extendable arm of the one or more extendable arms; an X-ray detector; and a control unit coupled to the robotic arm, the X-ray source and the X-ray detector, wherein the control unit is configured to control the movement of the extendable arm and the column member for moving the X-ray source along a path to perform tomography imaging of a subject.

Abstract: A method for image correction in a mobile X-ray device includes obtaining an X-ray image corresponding to a region of interest, where the X-ray image includes a projection of the region of interest by an X-ray beam on a detector plane. The method further includes receiving a tilt parameter corresponding to the detector plane. Moreover, the method includes generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, where the corrected X-ray image corresponds to a projection of the region of interest on a corrected detector plane.
