The miniaturized x-ray machines in dentistry: structural integrity and safety of the extended-anode tubes.
Two different designs of the extended-anode x-ray tube were evaluated for structural stability and safety. Force-deflection curves were determined in bending and compression modes. Although the tubes experienced similar deflection characteristics, one demonstrated several design advantages. Both machines were judged adequately safe during reversed-geometry film exposures, based on the ability of the rod anode x-ray tube to rotate in its suspension arm.
