Paper Abstract

This paper describes the psychophysical evaluation of a prototype electronic viewing console developed by the Toshiba Corporation. The evaluation consisted of two phases. In the first phase, four radiologists viewed 10 pediatric images. Each image was viewed first with no enhancement, second with window and level, and third with pan and zoom. A diagnosis and certainty was recorded for each of these viewings. The areas under the curve (AUC) were 0.80, 0.86, and 0.91 for no enhancement, window and level, and pan and zoom, respectively, compared to an AUC of 0.90 for film. The second phase was a clinical comparison of the capabilities of this electronic system to those of conventional film and computed radiography using cholangiography studies of the biliary system. Thirty-six images were viewed by five radiologists, and free use of enhancement functions was allowed. The areas under the curve for the images seen on the viewing console, conventional film, and computed radiography film images were 0.84, 0.84, and 0.83, respectively. The authors conclude that for examinations of these anatomic regions, pediatric chest and cholangiograms, each of them depicting a variety of pathologic processes, electronic viewing consoles seem to convey the needed information for accurate diagnosis.
