Initial results for a new technique of imaging the small and rapidly moving coronary arteries using linear arrays of self-scanning diodes coupled directly to a computer are described. The technique involves a thin, fan shaped x-ray beam and a phospho

In order to subjectively determine acceptable dose levels for portable CR, two blind experiments were performed while maintaining conventional screen-film radiography as a reference quality. In the first experiment, a team of two technologists and tw

In a series of large ROC studies, the authors analyzed the time radiologists took to diagnose PA chest images as a function of observer performance indices (Az), display environments, and difficulty of cases. Board-certified radiologists interpreted

In an ongoing, multi-reader, multi-project program dealing with the interpretation of radiological images, we have examined several issues of methodology which have not as yet been addressed that may impact on the determination of reader performance

Forced-choice just noticeable difference (JND) studies are extremely sensitive to image quality variations that are below the threshold at which the differences are apparent to or definable by the observer. Paired comparisons of 4K and 2K laser-print
