Abstract

Radiographic resolution and image sharpness are analyzed as a function of magnification for a few screen/film systems and a microfocal spot xÃ¢â‚¬Â�ray tube. Resolution and sharpness are described in terms of both MTF and effective aperture. The analysis demonstrates advantages of magnification for any combination of radiographic screen/film system and xÃ¢â‚¬Â�ray focal spot, and, in addition, allows one to compare different screen/film systems each used at different magnifications. Such an analysis is applicable to any radiographic system and may serve as a guide in selecting screen/film systems for use in magnification procedures.
