vertical angulation

The position of the dental x-ray tube head in the vertical plane, measured in degrees. The central ray is directed perpendicular to the film and the tooth when using the paralleling imaging technique. When using the bisecting angle technique, the central ray is directed perpendicular to the bisector. Errors in calculating the vertical angulation produce elongated or foreshortened images.
