DQE (detective quantum efficiency) and MTF (modulation transfer function) of a few radiographic luminescent sensors were calculated according to the simple analytical model (originally developed by Swank and reformulated by the authors). Next, these parameters were determined using the specialized Monte Carlo simulation program and compared with analytical results. The discrepancies were discussed, and constructive conclusions for more sophisticated analytical models were formulated.
