  • Publication number: 20150023468
    Abstract: A portable x-ray system includes a light weight x-ray head including an x-ray tube and a high voltage (HV) tank, wherein the HV tank comprises a compact voltage multiplier configured to receive a low voltage signal and generate a high voltage signal based on the received low voltage signal. Also, the portable x-ray system includes a carrying case comprising low voltage power electronics coupled to the light weight x-ray head through a low voltage cable, and configured to send the low voltage signal to the light weight x-ray head. In addition, the low voltage power electronics is distributed in a predefined space in the carrying case in such a way that a weight of the light weight x-ray head is counter weighed by a weight of the low voltage power electronics to stabilize the portable x-ray system when the light weight x-ray head is rotated in one or more directions.

  • Patent number: 8923484
    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.
