We performed an image quality simulation for the line scan system, which realizes a compact and high-speed Computed Radiography (CR) system. The line scan system uses a line light source and a linear CCD sensor. In this system, the emitted light must be efficiently focused onto the CCD sensor to detect the emitted light as much as possible. To realize the effective light detection, we analyzed the spread of the light in the photostimulable phosphor layer. We also estimated the image quality based on X-ray absorption, the amount of emitted light, light collecting efficiency and electric noise. It clarified the image quality is affected strongly by such factors as the spread of the PSL, the size of photo diodes of the CCD sensor and electric noise.
