Abstract
A simple, reliable, convenient and safe system for aiming a dental X-ray apparatus at an X-ray film plate. In the system of the present invention, magnetic field sensors, mounted on the dental X-ray apparatus, are used as a means of detecting the relative strength of a magnetic field of a magnet which is located next to an X-ray film plate within the mouth of a patient. By measuring and comparing the relative strengths of this magnetic field at each sensor, the system of the present invention can detect and indicate the condition of alignment or misalignment, including relative displacement in the x and y directions, as well as relative tilt about the x or y axes. Furthermore, the alignment system of the present invention can indicate misalignment of the X-ray film plate axes with the axes of the collimated X-ray beam. The present invention also provides a three-dimensional display by which the alignment or misalignment of the X-ray apparatus is conveniently indicated to the operator.
