资源简介:
Each image was exposed for 20 s using a flat panel detector with a pixel size of 50 μm and a 7 μm focal spot X-ray source. The voltage of X-ray source was 40 kVp and the current was 200 μA. The sample was a PMMA rod with a diameter of 3 mm, and the distance between object and X-ray source was 0.75 m.
