Abstract
The aim of this study was to review the basic points in the LSF measurements of the intensifying screen by MIC system(Microscope-Image intensifier-Charged coupled devicesystem). The results obtained were as follows:
There was a significant difference between the LSF calculated from the intensifying screen film combination and LSF obtained directly from the MIC system. The LSF obtained from the MIC system was much sharper. In the case of LSF measured for the combination of the intensifying screen and the film, multiple light reflection of the fluorescence occurred in the space between the intensifying screen and the emulsion layer of the film, and it is deduced from experiments that this contributed greatly to the impairment of sharpness. Controlling this phenomenon enables development of new system that will satisfy the opposing factors of high sensitivity and sharpness of the intensifying screen film combination.
