  • Means for visually indicating an X-ray field
    Patent number: 4502147
    Abstract: A visual indicator for an X-ray field includes a light generator providing a beam of light. The light is provided to a first mirror that moves about an axis normal to the beam of light to deflect the beam. The deflected beam is applied to a second mirror that moves about an axis normal to the first axis and applies the beam of light to a mirror on the axis of the X-ray beam for reflection onto the X-ray field. The mirrors are controlled by signals indicative of the field defining collimator leaves to cause the light beam to trace out the field defining by the collimator leaves.
