1. Laser guides for an X-ray device, the X-ray device being aimed at and aligned with a receptor such as X-ray film, and such X-ray device having an emitter capable of projecting X-rays through a patient or object and creating a X-ray image or such patient or object upon said receptor, and such X-ray device further being capable of being moved closer to or further from said receptor such that said X-ray device is at the optimum distance from said receptor and the X-ray beam is centered upon the receptor to create a clear and focused X-ray image, comprising: (1) a pair of brackets affixed to said X-ray device, or to any attachment which moves in concert with said X-ray device, such that the X-ray device emitter and the two brackets are in the same plane which plane is perpendicular to said receptor, and one of said brackets being on either side of said emitter; and (2) a pair of laser beam projecting means, one being rotatably affixed to each of said brackets such that the laser beam projecting means are capable of being rotated parallel to said plane and affixed in a position after being rotated, and each of said laser beam projecting means project a laser beam toward said receptor and inward toward a line between said emitter and the center of said receptor such that the laser beams cross at a visible location and said laser beam projecting means may be rotated and affixed at a position such the said laser beams cross at an appropriate location which insured that said X-ray device is at the appropriate distance from said receptor and the X-ray beam is centered upon said receptor to insure that a clear and focused X-ray image is produced when the X-ray device is used; whereby, after said laser beam projecting means are properly calibrated, said X-ray device may be moved closer to or further away from said receptor until said laser beams cross at an appropriate location and the operator may be assured that said X-ray device is at the proper location from said receptor to take a clear and focused X-ray.
