摘要：
The spatial resolution of scintillator coupled CMOS sensor has been investigated for the conditions of the digital radiography by using unified MTF. The scintillator was FOP CsI with high resolution and the CMOS sensor has a pixel pitch of 48 mu m. The effects of initial dark signal of the sensor on the unified MTF were newly modeled considering different radiography conditions. This model showed well the contribution of the dark signal on the degradation of the spatial resolution, and it compared to the measured spatial resolution.
