Forensic skiagraphy.

Since roentgenograms are merely skiagraphs and not photographs, and since they are accordingly subject to erroneous interpretations or deductions, it would seem highly desirable that courts rely upon expert analysis of them, rather than demonstration of the negatives themselves. Such practice is customary in connection with clinical laboratory work, pathology, bacteriology and many other medical fields. Interpretations of skiagraphs should be clear, complete and consistent.
