Toward Computed Detection of Nodules in Chest Radiographs

The detection of pulmonary nodules is recognized by radiologests as an important segment of the analysis and diagnosis of chest radiographs. Garland (1950) and others have demonstrated that radiologists routinely miss about 30% of the abnormalities visible in chest film radiographs. Ziskin et al. (1971) show that radiologists produce about as many or more false positives than false negatives when they search for a solitary nodule in a chest radiograph.
