Abstract: X-ray scanning methods and systems are provided in embodiments of the present inventions. According to one illustrative implementation, an exemplary method may comprise: collecting background data when no X-ray is emitted; collecting air data when X-rays are emitted and there is no object to be scanned in an inspection channel; scanning an object to collect original scanning data; and preprocessing the original scanning data according to the background data and the air data to acquire scanned image data. In some embodiments, when performing an X-ray scanning of a static object, implementations may measure the background data and the air data and process the scanning data, thereby solving noise issues caused by mechanical vibration and thus improving the measurement accuracy.
