Minimum detectable gray-scale differences in nuclear medicine images.
An analysis of the effects of display-system characteristics upon the image from a nuclear medicine imaging system is presented. Simple, quantitative relationships are developed for calculation of contrast values for a minimum detectable lesion and maximum useful image count densities, from the slope of the D-log E characteristic curves of different films. The results provide a practical aid in the selection of films for various nuclear medicine imaging procedures.
