Quizplus · Accepted Answer

The central ray of the x-ray beam should be directed perpendicular to the mean tangent to avoid overlap error. This means that the central ray should be directed at a 90-degree angle to an imaginary line drawn tangent to the area being imaged. If the central ray is not perpendicular, it can result in overlapping structures and inaccurate imaging.
