Abstract
A head positioner for positioning a patient's head properly for a cephalometric x-ray, or other type of imaging device, and for maintaining the patient's head in a proper position throughout an imaging session, comprises a mounting portion including a mounting plate and a positioning portion connected to the mounting portion by a support member. The mounting portion includes a mounting plate and a vertical height adjustment for vertically shifting the support member and the positioning portion. The positioning portion includes a pair of sliding headpieces engagable with the patient's head for properly positioning the same for imaging. An adjusting mechanism is operatively connected to the headpieces for coaxially positioning the headpieces symmetrically in unison a variable distance apart to accept heads of different dimensions. One of the headpieces is rotatable out of alignment with the other headpiece to allow initial placement of a patient's head in the positioner.
