Intraoral radiograph alignment device

摘要

The invention is an apparatus for use in serial radiography which provides replicable projection geometry between an energy source, an intraoral target area, and an image receptor. The device uses a stent and an alignment arm which terminates in an alignment ring. The alignment ring is received by a sensor ring affixed to an x-ray source to provide proper projection geometry. Sensors in communication with electronic means may be disposed about the sensor ring to indicate proper alignment.
