Paper Abstract

The characteristics of a novel, very high resolution film/screen system for mammography are compared with those of a conventional film/screen system for mammography. The image quality characteristics of these systems are measured in terms of Wiener spectra, MTF and sensitometry. These parameters then determine the signal-to-noise (SNR) transfer properties of these systems in terms of the contrast transfer function (CTF), the detective quantum efficiency (DQE) and the noise equivalent quantum efficiency (NEQ). Furthermore, the SNR transfer characteristics are modeled and rationalized by means of the light scattering properties of the intensifying screens and the scintillation spectra of the phosphor. The new system displays superior SNR properties ascribable to its x-ray absorption attributes and the light scattering properties of the phosphor coating.
