Abstract

The contrast transfer function (CTF), noise power spectrum (NPS), noise equivalent quanta (NEQ), and detective quantum efficiency (DQE) of a high-resolution screen-film combination have been measured for exposure to a 30 kVp x-ray spectrum. In addition to these overall system characteristics, selected component sources of noise in the screen-film combination have been determined experimentally. These data are interpreted in terms of a simple model which is used to predict screen-film NPS, NEQ, and DQE. Reasonable agreement between model predictions and experimental measurements has been found.
