Savannah River Technology Center filmless radiographic imaging system specialists have been “champions” of filmless radiographic imaging at the Savannah River Site since 1993. Recently a study was done comparing the differences between conventional film radiography and lens-coupled, charge-coupled-device digital radiography. Characteristics of both imaging methods that were considered in the study included resolution, latitude (called dynamic range by digital radiography imaging specialists), and modulation transfer functions. The results of those comparative experiments will be presented. A description of the lens-coupled, digital radiography imaging system will be provided.
