  • The portable low-intensity x-ray real-time imaging system was composed of Lixiscope, the image collection and procession system of CCD. Recently, people pay more attention on it due to its wide applications. In this paper, the structure and characteristics of CsI/MCP photocathode was briefly given. The controllable main factors (image noise and aberration) which influence the imaging quality of the image tube (single single-proximity focusing x-ray image intensifier) were analyzed. The method to improve the image quality by decreasing the working voltage of MCP was proposed. At the same time, the other method such as cooling CCD, prolonging the integration time and image-processing were also studied. The optimized resolution (6.3lp/mm) was obtained which can achieve the anticipated goals to decrease the flashing noise and ensure the brightness of the image. Using this system, the industrial product, the finger of human body and so on can be detected and diagnosed. The corresponding pictures were given which indicating an wide applications of this new type of low-intensity x-ray real-time imaging system.
