In this study, we demonstrate X-ray imaging performance of our digital X-ray imager with 20 - 110 kV X-ray tube, and combination of various gas (Ar/CF4, Kr/CF4, Xe/CF4). The imaging system shows high sensitivity to low-energy X-rays, which results in a high contrast radiograph for elements with low atomic numbers. In addition, high spatial resolution and high speed image forming is demonstrated with taking X-ray movies in 10 ms integration time.
