A recently developed model uses the localization of abnormalities on images to improve statistical precision in measuring detection accuracy Az, the area below an observer's receiver operating characteristic (ROC) curve for ratings of sampled normal

In this paper methods used to measure observer performance are reviewed, and a simple general model for finding and reporting target objects in gray-scale image backgrounds is presented. That model provides the basis for a combined measurement of det

Rationale and Objectives. Many perceptual studies have shown that the detection of large, low-contrast targets is better either in color or in contrast-reversing presentations than in standard gray scale. We determined the value of several new displa

This study evaluated the relative roles of physical and perceptual factors in flattening the contrast-detail (CD) curve on liver CT scans. To estimate the role of physical factors, the theoretical CD curve for a calculated theoretical observer (i.e.,

Contrast‐detail curves were constructed for liver computed tomographic (CT)images using an objective method. Stimuli were created by superimposing disks at specified locations on sets of 92 normal liverCTimages. Bright and dark disks of 9 sizes and

A questionnaire was mailed to 708 practicing radiologists and 348 members of the Society for Computer applications in Radiology (SCAR) in order to evaluate current practices and attitudes regarding the perceived advantages or disadvantages of film- a

This paper proposes a simple, but general, model for describing an observer's ability to find and report target objects in grayscale image backgrounds, which provides a basis for measuring the observer's combined detection- and-localization performan
