RATIONALE AND OBJECTIVES To assess the performance of an experimental prototype dual-energy (DE) chest imaging system in comparison to digital radiography (DR) in detection and characterization of lung lesions using receiver-operating characteristic (ROC) tests. MATERIALS AND METHODS A cohort of 129 patients (80 M, 49 F; mean age, 64.8 years) was drawn(More)
PURPOSE To study the effects of exposure error on the clinical utility of chest radiographs. MATERIALS AND METHODS Under- and overexposed screen-film images were simulated by adding exposure offsets to the normalized CR log(10) exposure data from a computed radiography (CR) system and printed by using the sensitometric response of a medium-latitude(More)
