Abstract
A model is presented that predicts contrast detectability and resolvab ility in 3D X-ray computerized tomography images as a function of X-ra y source energy, area detector type, data collection hardware, and oth er system parameters. The model has been found to agree well with expe rimental observation and to compare favorably with prior theoretical m odels. This model is used to evaluate the performance of eight differe nt area detector configurations in a micro-focus X-ray system used to inspect small ceramic components. Predicted performance is consistent with that of known systems and serves to illustrate the complexity of imaging system design.
