To determine the vertical angulation when using the bisecting technique, the central rays of the x-ray beam should be directed:
A) perpendicular to the image receptor.
B) parallel to the image receptor.
C) perpendicular to the imaginary bisector.
D) parallel to the imaginary bisector.

Question

Quizplus · Accepted Answer

When using the bisecting technique, the vertical angulation should be determined by directing the central rays of the x-ray beam perpendicular to the imaginary bisector, which is an imaginary line that bisects the angle formed by the long axis of the tooth and the plane of the image receptor. Therefore, choice C is the correct option.
