Abstract: This paper describes a special double coated X-ray film designed with a rcflecting-isola-tion layer between the emulsion layer and the base for both sides. Using this structure, the effect of crossover exposure can be eliminated. The sensitivity of such special structure film is about 25% higher than that of the ordinary film (with same emulsion) and the modulation transfer function (MTF) of such film, with intensify seren, was measured with X-ray is much higher (25%-50%, depending on the spacial frequency from 0.1 to 31 p/mm) than that of the ordinary film.

Key words: X-ray film, image quality, crossover exposure, modulation transfer function
