Conventional viewing of radiographic image is done by placing film on a flat light box. In a filmless radiology system, CRT monitors are used in the place of the light box. Curvature of the viewing area of the conventional CRT requires radiologists to adjust their habit and experience to the new display geometry. This may result in the accuracy of the diagnosis. This paper presents a newly developed 22‐inch naturally flat, gray scale CRT monitor for light box style viewing. CRT optical performance including modulation transfer function (MTF) will be presented. A unique deflection design and technique will be discussed.
