What does it indicate when linear measurements can be used with pantomographs?

When pantomographs, or panoramic radiographs, allow for linear measurements to be used, it indicates that the image produced maintains consistent magnification across its entire area. This consistent magnification is essential for linear measurements to be accurate, as it ensures that the proportions and distances represented on the image do not vary at different points. In other words, every measurement taken from the pantomograph translates reliably to real-world dimensions, enabling clinicians to make informed assessments about a patient’s oral structure.

Achieving consistent magnification is a key characteristic of a well-calibrated panoramic imaging system, which minimizes distortion and provides a more reliable basis for evaluating anatomical features.
