Focal trough and patient positioning

Panoramic radiography is a common imaging modality used in dentistry. Panoramic radiographs provide an overall view of the dentomaxillofacial complex and are often used along with intraoral radiographs during the diagnostic phase of patient treatment. In recent years, identification of potential stroke victims has been included as a benefit of panoramic radiographs. This has stimulated an increased interest in panoramic radiography both by oral and maxillofacial radiologists and by general dentists.
