Abstract
A marble statue of Caligula at the Virginia Museum of Fine Arts is imaged using NDT Scan IV, the first film digitizer for non-destructive testing, to study the join between the head and the neck. It was the custom of the times to lop the heads off statues of deposed emperors. The head of this sculpture had been knocked off and the two sections were stored separately for some period, but the patina and workmanship has led most art historians to conclude that they belong together. A conservation treatment in 1970 rejoined head and body with an epoxy compound, making the joint difficult to study, so a day-long radiography session was scheduled to study images at varying thickness. The NDT Scan IV workstation enables radiographers to interpret film images more accurately. Density shift, contrast stretch, edge definition, and image magnification can all be used to make the information easier to visualize.
