Paper Abstract

For more than five years now the Bureau of Radiological Health has been making quantitative measurements on the physical imaging parameters of radiologic imaging systems' components. This work has taken place in the laboratories of the Bureau's Divison of Electronic Products. Our earliest efforts addressed questions concerning the performance of films, intensifying screens, and the x-ray tube focal spot. In order to seek a consensus on methods for measuring such quantities as sensitometric response, modulation transfer function (MTF), and noise power spectra for film/screen systems, MTF and summary measures of performance of focal spot, image tubes, and n9w image detection schemes, we presented a symposium entitled "Medical X-Ray Photo-Optical Systems Evaluation" in Columbia, MD in October of 1974. Many of the papers presented by experts in the field at the Columbia symposium might well serve as draft documents for standardization of several measurement techniques, most notably those on film/screen systems.
