A method to determine the impact of reduced visual function on nodule detection performance

Abstract

A method to assess visual function and observer performance is proposed. In this pilot evaluation we were unable to detect any difference in nodule detection performance when using lenses to reduce visual function.

Reduction of visual acuity decreases capacity to evaluate radiographic image quality

“…VDU syndrome is sometime that Occupational Health practitioners have introduced guidelines. However, when it comes to image quality analysis by radiographers, there have been papers considering radiographers as mammogram reporters 29 , some considering the method and doing preliminary investigation of the literature 30,31 which concluded "Further studies are necessary to understand fully the relationship between visual performance on tests and diagnostic accuracy in practice". Accordingly, this study has the following objectives: a) to determine the impact of reduced visual acuity on a simple task (object counting in a phantom); and b) assess the impact of reduced visual acuity on the technical evaluation of appendicular radiographs.…”
