Abstract

We present the results of calculations concerning the modulation transfer function (MTF) of the thin transparent foils used in the radiographic cassettes between the phosphor material of the screen and the film. For these calculations we have taken into account the real spatial distribution of the light emitted from a phosphor screen which diverges from the Lambert law depending on the characteristics and the structure of the screen.
