The purpose of this study was to clarify the basic points in MTF measurement of the intensifying screen and film combination. The LSF mesurement was carried out by the slit method. The results obtained were as follows:<BR>In the MTF mesurements of intensifying screen, in case that the LSF was calculated in conventional manner by the combination of intensifying screen and film, it was shown experimentally that there were differences in LSF depending on the developmental condition.<BR>It was shown that the LSF obtained by low gamma developmental processing had narrow width than that by high gamma processing.<BR>It was concluded that this phenomenon was caused by the effect of the light irradition from the high-density part of the slit image.
