| Abstract |
The purpose of this study is to investigate the feasibility of a novel indirect flat panel detector (FPD) systemfor removing scatter radiation. The substrate layer of our FPD system has a Pb net-like ...structure that matchesthe ineffective area and blocks the scatter radiation such that only primary X-rays reach the effective areaon a thin-film transistor. To evaluate the performance of the proposed system, we used Monte Carlo simulationsto derive the scatter fraction and contrast. The scatter fraction of the proposed system is lowerthan that of a parallel grid system, and the contrast is superior to that of a system without a grid. If thestructure of the proposed FPD system is optimized with respect to the specifications of a specific detector,the purpose of the examination, and the energy range used, the FPD can be useful in diagnosticradiology.show more
