Improper central ray alignment will distort a radiographic image. When used with the Collimator Test Tool, this device provides a simple means of determining if the x-ray beam is perpendicular to the image receptor and centered with respect to the light field. A steel ball is mounted in the center of a disc at each end of the 15cm high clear plastic cylinder. When the balls are positioned over one another and at a right angle to the film, their images will appear as one if the central ray is truly perpendicular to the film.The approximate degree of improper angulation can also be determined.
