Head positioning apparatus and method for cephalometric imaging

摘要

A apparatus is described for positioning the head of a patient for taking various x-ray images of the head. The head-positioning apparatus contemplates an arm member rotatably mounted to a pivot member for rotating the arm about an axis of rotation and at least one ear locating member coupled to the arm member in which the ear locating member rotates with the arm member and in alignment with the axis of rotation. The apparatus also contemplates an x-ray emitting source and an indicator coupled to the x-ray emitting source to provide the indicator and x-ray emitting source to rotate in conjunction and same direction with each other, in which the indicator locates a plane alignable with an ear of the patient.
