Psychophysical contrast and resolution responses obtained from r.diologists in two experimental studies are compared with similar data from previous work by the authors. Five observers participated in two experiments that were designed to compare the effectiveness of two video systems (a standard system set at 525 scan lines and a high-resolution system set at 1023 scan lines) for displaying nodules of different size and contrast. We co elude, based on the results of all studies, that video systems exist that have a sufficient contrast transfer to allow detection accuracy similar to that achieved with film.
