Methods of Improving on Image Quality of Real-Time Radiography Inspection

New methods were proposed to improve the original X-ray image quality. The distortion of X-ray image caused by remnant magnetism of steel pipe was avoided by adopting additional magnetic field. The noise of X-ray image caused by X-ray scattering was reduced by additional lead pieces. The noise of X-ray image caused by electro magnetic interference was decreased by proper assignment of power supply. And the definition of X-ray image was improved by properly selecting of X-ray source and its focus.
