Abstract
An investigation of the signal, noise and signal-to-noise transfer properties of a Fuji 7000 series computed radiography (CR) system using third-generation storage plate technology has been undertaken. The results show a significant improvement in signal-to-noise performance of the system compared to an earlier generation of CR technology. Results of the CR evaluation compare favourably to those obtained from a selection of rare-earth screen-film systems evaluated under identical exposure conditions. These results were further substantiated by results from threshold contrast-detail detectability tests.
