Abstract
Reliable studies show that under routine conditions radiologists fail to detect approximately 30% of abnormalities present on chest x-ray films. These failures of detection are perceptual in nature and not due to limitations in such physical parameters as resolution or contrast. There are many image processing techniques that are being proposed to help the radiologist. Most of these techniques have been implemented by us in TV process-ing of x-ray films. Each processing technique was evaluated experimentally using radiologists as observers in a test based on concepts originating from signal detection theory. A numerical value for d', an index of merit, was assigned to each technique according to how well it improved the accuracy of the radiologists' decision making.
