Computed radiography incorporates innovative phosphor technology and scanning laser stimulated luminescence to convert X- or gamma- radiation into a digital file that can be arranged and viewed like a radiograph on a computer display. This relatively new approach to radiography represents a more affordable and practical alternative to film as an imaging process for some nondestructive inspection applications. This presentation describes the computed radiography (CR) `process' with special emphasis focused on the CR phosphor. The similarities and specific advantages that the CR process has over a film based system are presented. CR has been identified to be more practical and affordable than either film radiography or ultrasound in five aerospace NDT applications. Laboratory evaluations of these applications are discussed.
