A Poorly Positioned AP Axial Cranial Projection (Caldwell Method) Demonstrates

Multiple Choice

A poorly positioned AP axial cranial projection (Caldwell method) demonstrates the petrous ridges inferior to the infraorbital margins. How could the positioning setup be adjusted to obtain an optimal projection?
1) Rotate the patient's face toward the left side.
2) Adjust the central ray angulation caudally.
3) Tuck the patient's chin until the OML is perpendicular to the IR.
4) Elevate the patient's chin until the OML is perpendicular to the IR.
