Abstract

LCDs age, and as they do so the whitepoint shifts to a yellow hue. This changes the appearance of the displayed images. We examined whether this shift impacts observer performance and visual search efficiency of radiologists interpreting images. Six radiologists viewed 50 DR chest images on three LCDs that had their whitepoint adjusted to simulate monitor age (new, 1-year old, 2.5 years old). They reported the presence or absence of nodules along with their confidence. Visual search was measured on a subset of 15 images using eye position recording techniques. The results indicate that there was no statistically significant difference in ROC performance due to monitor age (F = 0.4901, p = 0.6187). There were not statistically significant differences between the three monitors in terms of total viewing time (F = 0.056, p = 0.9452). Dwell times for each decision type did not differ significantly as a function of monitor age. The shift in whitepoint towards the yellow range (at least up to 2.5 years of age) does not impact diagnostic accuracy or visual search efficiency of radiologists.
