Paper Abstract

A study was performed to characterize the response of five different film screen combina-tions for potential application in cephalometric radiographic studies. These film screen combinations included Kodak T-Mat G, T-Mat L and XL-films in combination with Lanex Regular and Lanex Medium screens plus XL-film with a Par Speed screen. The response of the film screen combinations evaluated were characterized by the use of contrast detail response functions. These functions were determined with a minimum of six observers, trained and untrained, for each of the image receptor combinations evaluated. The images for evaluation in this study were generated using a low contrast "Rose Burger" phantom with optical densities from 0.5 to more than 1.0 for all of the film screen combinations evaluated. Also included are the relative dose-density data for the film screen combination images evaluated.
