In the proximity of X-ray imaging systems based on X-ray image intensifier, pixel matching and noise suppression are
important methods to improve image quality. This paper analyzes CCD parameters’ impact on imaging quality and the
relations with, proposes pixel matching degree is a critical factor to restrict the performance of imaging system, and
verified by experiments, the CCD refrigeration can effectively suppress the image noise, which adopts the extension of
integration time method and obtains favorable signal-to-noise ratio, it also provides a simple and low cost solution for
high quality X-ray real-time imaging of static objects.
