Predictive Model of Key Performance Measures for Computed Radiography

A system image quality model that can predict computed radiographic image performance from the engineering parameters of any subsystem component would be a valuable tool to reduce the cycle time in the development of new systems. This paper describes the model, its adaptation for NDT applications, and the verification of the target generation and image simulations for NDT purposes.
