  • X-ray device having a co-axial laser aiming system in an opposed configuration
    Patent number: 5283808
    Abstract: An improved x-ray laser aiming system providing coaxial laser aiming in a configuration opposed to the x-ray emitter is disclosed. The present invention comprises two basic components: 1) a laser sight coupled to an x-ray emitter, and 2) a laser housing coupled to an x-ray collector. The laser sight provides a means for aligning the x-ray emitter with a laser beam during surgical or diagnostic procedures. The laser housing is removably coupled to the image intensifier or x-ray collector. The laser housing contains a point laser source and a fixed reflective surface or mirror for directing a laser beam coaxially with the center ray of the x-rays emitted by the x-ray emitter, but in the opposite direction. The laser source is, therefore, in a configuration opposed or opposite to the x-ray emitter.
