A panoramic-cephalometric x-ray (also sometimes called simply a' ceph') is a diagnostic radiograph used for orthodontic treatment planning. Cephalometric x-rays are also often used by doctors who specialize in ear, nose, and throat disorders like sleep apnea — because these x-rays provide a view of the patient's airways. With the adoption of more technology into dentistry, Panoramic Cephalometric dental x-ray equipment continues to grow in importance.
