| Abstract: | An electro-optical system for digital radiographic apparatus is designed. The system consists of converting screen, light path, CCD camera and computer processing circuit. X-ray image is converted into visible image by using CsI (TI) single crystal scintillation screen, optical image is converted into electric signal with scientific grade CCD and image sampling is carried out by using computer parallel port. The experiments demonstrate that its image quality is better than that of the imaging system formed with image intensifier and it is suitable for the scene of high-quality imaging. |
