摘要： A motion correction system and method for motion correction for an x-ray tube is presented. One embodiment of the motion correction system includes a sensing unit coupled to an x-ray tube to determine a distance with which an impingement location of an electron beam generated by the x-ray tube deviates from a determined location due to motion of the x-ray tube. The motion correction system further includes a control unit coupled to the sensing unit to generate a control signal corresponding to the distance with which the impingement location of the electron beam deviates. Also, the motion correction system includes a deflection unit coupled to the control unit to steer the electron beam to the determined location based on the generated control signal.

摘要： A technique for directly reconstructing three-dimensional images acquired in tomosynthesis imaging is provided. The method allows for pre-processing a set of projection images based upon the acquisition geometry prior to direct reconstruction of the projection images. Furthermore, the technique allows for post-processing the reconstructed image data as desired to improve image quality. If desired the direct reconstruction process may be iterated a set number of times or until a desired threshold criteria is met, such as regarding image quality.
