Imaging performance of a digital storage phosphor system

摘要: The imaging performance of a storage phosphor system (SPS) for digital projection radiography is studied in which the x‐ray image temporarily stored light‐stimulable plate subsequently read out by scanning laser beam. this has been analyzed two types plates. spatial resolution described modulation transfer function and signal‐to‐noise (S/N) ratios recorded data are measured terms noise‐equivalent quanta detectivequantum efficiency. Their dependence on detector entrance dose space frequency discussed. A detailed analysis different sources noise given to outline intrinsic features limits system. Finally, S/N behavior SPS compared with published screen–film systems.
