OSTI ID:5638358
Two different areas of a focal trough of a dental arch structure are simultaneously displayed on a radiograph when tubehead-camera assembly of an x-ray machine panoramically scans the dental arch structure. The different areas of the focal trough are obtained when a pair of parallel disposed film holding devices within the camera are caused to travel in proximate relationship to each other at different speeds. The x-rays activate and pass through one film before activating the other immediately therebehind.
