What are the fundamentals of panoramic radiography?
PRINCIPLES OF PANORAMIC RADIOGRAPHY In panoramic radiography, the x-ray source and the film are connected to each other. These two components rotate simultaneously around the patient to produce an image. The three-dimensional, horseshoe-shaped zone where images are sharp is called the focal trough, or image layer.

What is the patient’s position during a panoramic imaging?
