Incorrect Vertical Angulation: positioning the central ray so that the vertical angulation is too flat (less than the optimal +10 degrees) provides an image that is elongated, or too long in the vertical dimension. This angulation allows the x-ray beam to pass through the contacts of the teeth, allowing a clear unobstructed (open, without overlap) view of the interproximal surfaces of the teeth. Which tissue is lowest for relative radiation sensitivity? When a film passes through fixer solutions before developing, the film will appear clear.

The creation of ideal and diagnostic images is challenging and depends on good technique. It is challenging to apply the work proposed for bitewing images directly to panoramic images because they are structurally different.
