ABSTRACT:
A dental x-ray alignment device is described for attachment to the extension tube of the x-ray unit. The device has a cylindrical conical frustum exterior shape with a central opening adapted to frictionally reside on the extension tube. An annularly shaped conical cavity is formed in the sidewalls of the cylindrical conical frustum, the cavity being open on one end joining the front face of the frustum. A plurality of light emitting sources are situated in the base or bottom of the frustum to emit light from the open end of the cavity. The light is projected onto the patient's face to circumscribe the x-ray beam pattern for certainty of x-ray beam placement during procedures. In an alternate embodiment, the invention is incorporated into the coupler and extension tube normally attached to the x-ray unit head. In this embodiment, an annularly shaped open-ended cavity is formed around a cylinder replacing the extension tube with the plurality of light emitting sources situated in the base of the cavity to project a circle of light onto the patient's face and jaw.
