A physical evaluation of the imaging performance of a high-resolution fluorography system

AR Cowen
Radiological Imaging Group, University of Leeds.

A physical evaluation of the imaging performance of a unique high-resolution fluorography system is presented. Measurements have been made of contrast performance, unsharpness (modulation transfer function) and noise (Wiener spectrum and threshold contrast detectability), and the results have been compared with those measured from medium-fast calcium tungstate and rare-earth screen--film combinations and a standard fluorography system. The results have proved sufficiently encouraging that a full-scale trial is now underway to evaluate the system's performance in routine clinical application.
