Abstract
Xeroradiographic and radiographic film image analysis through application of the radiographic modulation transfer function defined in this paper is a powerful analytical tool. This tool has been found to predict spatial and densitometric characteristics of an x-ray image for an arbitrary set of input object exposures and contrast variations with sufficient accuracy to allow meaningful comparisons of different types of radiographic imaging systems. This paper presents a simple computerized technique for the derivation of the radiographic modulation transfer function from the image of a knife edge test object. Techniques used for assessing the degree of system linearity over the output response range of interest and the role of the system phase response are also presented. Typical xeroradiographic, screened and unscreened film radiographic modulation transfer functions derived with the program are compared and discussed in the conclusion to the paper.
