Method for identifying artifactual radiographic images caused by epithelial protuberances

摘要: The present invention provides a method for identifying the artifactual radiographic images caused by epithelial protuberances. claimed employs partially radiolucent, faintly radiopaque marker which is secured around an protuberance. designed so that when it not only preserves generally cylindrical shape and vertical boundaries of protuberance, but also ensures thin layer or film air maintained surrounding After secured, preserved protuberance are presented tangentially to xray beam produce shadow both marker. image can then be readily identified detecting cast in association with surrounding, opaque
