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.
Abstract translation: 一种牙科X射线对准系统，其中安装在牙科X射线装置上的各种霍尔效应传感器检测由附接到位于患者口内的x射线胶片板的磁体产生的磁场强度。 通过测量和比较相对磁场强度，本发明可以指示牙科X射线设备何时被适当对准，并且还可以指示装置应该移动以获得对准的方向，以及设备和 电影板。 本发明还包括用于调节牙科X射线设备准直的装置。
