Good Agreement

An exponential equation can be used to characterize the line spread function (LSF) of the X-ray film/screen combination. The analytic Fourier transform of the LSF yields the modulation transfer function (MTF). Predictions using the theoretical model show good agreement with results btained by numerical Fourier transformation. A single figure of merit parameter may be assigned to the film/screen system. This parameter determines the system spatial frequency response.
