Abstract/OtherAbstract:
|
A high-density, unreadable cephalogram was made readable by duplicating it at 7 to 10 times the usual ultraviolet light exposure. Soft tissue images were retrieved from a readable cephalogram of normal density by duplicating it at 12 to 20 times the usual ultraviolet light exposure. However, the hard tissue images disappeared in the duplicating process. A correctly made duplicate radiograph had a higher image resolution than the image resolution of the original corresponding high-density radiograph. The difference was not significant clinically. |
