Patient erect or supine
Place the lateral side of head against IR
Oblique patient’s body as needed for true

Patient is erect with face toward IR
Place patients nose and forehead against IR
The OML should be 15 degree from
horizontal
Align mid-plane to mid-plane
No rotation or tilt

Patient is facing the same as Caldwell
Except place chin and nose against IR
MML perpendicular to IR
OML should form a 37 degree angle
No rotation no tilts
