    Abstract: An X-ray generator is provided using a transmission type target having a long life span, where it is possible to change the point for generating X-rays on the surface of the target while maintaining the vacuum chamber in a high vacuum state. A portion of a vacuum chamber 1 that includes a target 2 is linked to a main body portion 1a of the chamber through a linking member 5 as a movable chamber portion 1b. A fixed anode 12 is provided between the target 2 and the electrode 10 at the final stage from among a group of electrodes 8, 9 and 10 for electrostatically accelerating and converging electrons from an electron source 7 and is fixed to the main body portion 1a of the chamber in order to prevent the form of the electrical field from changing when the movable chamber portion 1b is shifted.

    Abstract: 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.
