Paper Abstract

Measurements of the performance of two high-resolution radiographic screen-film systems at 50 and 30 kVp are given in terms of the noise equivalent number of recorded x-ray quanta (NEQ) and the detective quantum efficiency (DQE). Additionally, the MTF, contrast transfer function (CTF), and noise power spectra (NPS) of these imaging systems are presented. The NEQ, DQE, CTF, and NPS are shown to be strong functions of both spatial frequency and exposure. The shapes of these surfaces are significantly different from those published for general-purpose radiographic systems; these data provide a useful context within which screen-film system performance can be interpreted.
