“…Muscular asthenopia is caused by strain in the external ocular muscles. There is no single cause of visual fatigue and the presence of visual fatigue may indicate any of several different oculo-motor control issues (Shen, Barbera, & Shapiro, 2006;Wijesuriya, Tran, & Craig, 2007;Krupinski & Reiner, 2012). Thus, visual fatigue may not be assessed adequately using only a single criterion (Saito, 1999).…”

“…Thus, visual fatigue may not be assessed adequately using only a single criterion (Saito, 1999). The commonly used visual fatigue evaluation indices include critical-flicker fusion (Lin, Chen, Lu, & Lin, 2008;Chan & Hsu, 2010), near-point accommodation (Yano, Emoto, & Mitsuhashi, 2004;Krupinski & Reiner, 2012), visual-evoked potential (Murata, Araki, Yokoyama, Yamashita, Okumatsu, & Sakou, 1996;Emoto, Niida, & Okana, 2005), eye-fixation-related brain potential (Yagi, Ikoma, & Kikuchi, 2009), eye blink (Philipp, Udo, & Peter, 2003), and subjective rating of visual fatigue (Kuze & Ukai, 2008). Each of these visual fatigue indices has its own unique physiological or psychological basis.…”

Electroencephalography (EEG) is widely used in cognitive and behavioral research. This study evaluates the effectiveness of using the EEG power index to measure visual fatigue. Three common visual fatigue measures, critical-flicker fusion (CFF), near-point accommodation (NPA), and subjective eye-fatigue rating, were used for comparison. The study participants were 20 men with a mean age of 20.4 yr. (SD = 1.5). The experimental task was a car-racing video game. Results indicated that the EEG power indices were valid as a visual fatigue measure and the sensitivity of the objective measures (CFF and EEG power index) was higher than the subjective measure. The EEG beta and EEG alpha were effective for measuring visual fatigue in short- and long-duration tasks, respectively. EEG beta/alpha were the most effective power indexes for the visual fatigue measure.

“…While a number of technologies currently exist to measure visual fatigue and physiologic stress [15], direct integration into imaging and information system technologies is not currently available. As a result, measures of occupational stress and fatigue among medical imaging professionals are largely limited to subjective and intrapersonal evaluation, which is not reproducible and difficult to quantify.…”

“…Customized presentation of image reconstructions Understanding the complex relationship between occupational stress/fatigue and quality of performance is a fundamental goal of the proposed technology, which is not present in existing SMIs. A number of quality metrics can be incorporated into the stress/fatigue database (Table 2), which can be used in the assessment of visual, physiologic, and cognitive forms of fatigue [15]. In addition to elucidating the relationship between fatigue and performance, these data can also be used in the creation of best practice guidelines, education/training tools, and workflow optimization.…”

Introduction: Visual search is a task that humans perform in everyday life. Whether it involves looking for a pen on a desk or a mass in a mammogram, the cognitive and perceptual processes that underpin these tasks are identical. Radiologists are experts in visual search of medical images and studies on their visual search behaviours have revealed some interesting findings with regard to diagnostic errors. In Australia, within the modality of ultrasound, sonographers perform the diagnostic scan, select images and present to the radiologist for reporting. Therefore the visual task and potential for errors is similar to a radiologist. Our aim was to explore and understand the detection, localisation and eye‐gaze behaviours of a group of qualified sonographers. Method: We measured clinical performance and analysed diagnostic errors by presenting fifty sonographic breast images that varied on cancer present and degree of difficulty to a group of sonographers in their clinical workplace. For a sub‐set of sonographers we obtained eye‐tracking metrics such as time‐to‐first fixation, total visit duration and cumulative dwell time heat maps. Results: The results indicate that the sonographers' clinical performance was high and the eye‐tracking metrics showed diagnostic error types similar to those found in studies on radiologist visual search. Conclusion: This study informs us about sonographer visual search patterns and highlights possible ways to improve diagnostic performance via targeted education.
