  • X-ray imaging system
    Patent number: 6568850
    Abstract: An X-ray imaging system has an X-ray head containing an x-ray source which emits an X-ray beam. The head is rotatable around a pair of orthogonal axes for orienting the emitted X-ray beam in space. A pair of head angle sensors are located with the X-ray head, each being associated with a different one of the pair of axes for measuring an angle of inclination of the X-ray head dependent on its rotation around its associated axis. A display is operably connected to each head angle sensor through a signal processing unit for providing a graphic displaying of angle information related to each of the measured angles collocated at a single viewing station.
