Abstract
A dental x-ray aligning system in which various Hall effect sensors, mounted on a dental x-ray apparatus, detect the magnetic field strength resulting from a magnet which is attached to an x-ray film plate located within the mouth of a patient. By measuring and comparing the relative magnetic field strengths, the present invention can indicate when the dental x-ray apparatus is properly aligned, and can also indicate the direction in which the apparatus should be moved to obtain alignment, and the distance between the apparatus and the film plate. The present invention also includes means for adjusting the collimation of the dental x-ray apparatus.
