Abstract

The goal of the study was to compare physical and psychophysical performance of a flat-surface CRT monitor vs a traditional curved-surface CRT monitor. Radiographs based on familiar projection techniques are planar images and are traditionally displayed by placing the film on a flat surface viewbox. Presenting them in digital form on a CRT with a curved surface may cause distortions, which might affect diagnoses, especially if the physical dimensions of the anatomy are important. Other problems with a curved surface occur due to reflections from ambient lights behind the observer. Two DataRay CRT monitors that had different types of front glass-panel surfaces were evaluated. The first was a traditional CRT monitor with a curved surface, the other was a CRT with a flat surface. Physical measurements included dynamic range, display function, veiling glare and spatial uniformity. The performance study used low contrast squarewave patterns to determine JNDs. Room lights were off in one condition and on in the other. For both studies, performance with the curved CRT was affected by ambient light - performance was better with lights off for the curved panel, but not very different for the flat panel with or without the lights on.
