Abstract

The Siberian digital radiographic device (SDRD) is in clinical use in Novosibirsk and Moscow where it produces images of high diagnostic value at considerably lower dose levels than conventional film-screen combinations. We have made contrast-detail measurements to compare its imaging performance with film-screen systems used in clinical practice in the UK. We have also compared clinical doses for Russian SDRD examinations with doses for the equivalent examinations in die UK. The SDRD performs better than the UK film-screen systems for large low-contrast objects at all exposure levels, and requires lower doses, by up to two orders of magnitude, when compared for a range of common examinations.
