By elevating the chin to place the acanthiomeatal line (AML) parallel with the floor, the ramus of the mandible will not obstruct the cervical spine on the radiograph. AML is an imaginary line that connects the acanthion (the point where the upper lip meets the base of the nose) to the external auditory meatus (the opening of the ear canal). It is used to align the head in radiographic imaging. Rotation of the skull (choice B), caudad angulation of the CR (choice C), or having the patient hold weights (choice D) would not prevent superimposition of the mandible and spine.
