The mandible parts of the individual can be visualized by the different PA positions and at different degrees which are CR directed. The patient's head can be directed into the different degrees.
The rami are well visualized when the patient is in the PA position. The CR directed 20 degrees 20° to 25° cephalad angulation makes the patient rami visible.
