Abstract(in English) | Recently, FPD(Flat Panel Detector) is used for a detector of medical x-ray imaging system. It is known widely that various noises included in medical x-ray image impede a diagnosis. Influence of quantum noise on the image taken with low dose is especially critical problem. WS(Wiener Spectrum) is used as evaluation of the noise, and it is calculated by FFT method, MEM method, and so on. However, WS calculated in these researches are based on data supplied by experiment. In this study, we calculated WS of FPD using extended checker-board model (ECBM) which was proposed by us, and compared FFT method with it to confirm utility of it. |
