An SMV Cranial Projection (Schueller Method) with Poor Positioning Demonstrates

An SMV cranial projection (Schueller method) with poor positioning demonstrates the mandibular mentum posterior to the ethmoid sinuses. How could the positioning setup be adjusted for an optimal projection to be obtained?
1) Tilt the patient's head toward the left side.
2) Angle the central ray cephalically.
3) Increase neck extension.
4) Align the IOML parallel with the IR.
