A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. The radiograph should be of sufficient diagnostic quality, and keep the radiation dosage as low as reasonably achievable (ALARA). moving or lying in the same plane, always separated by the same distance.
