This study reports the potential of eye-tracking technology in determining screening skills of cytotechnology (CT) students while examining digital images (DI).
Twenty-five static DI of gynecologic cytology specimens were serially displayed on a computer monitor for evaluation by 16 CT students and 3 cytotechnologists at 3 locations. During evaluation, participant's eye movements were monitored with a Mirametrix S2 eye tracker (iMotions, Boston, MA) and EyeWorks software (Eyetracking, Solana Beach, CA). Students completed the protocol at: Period1 (P1)-4 months, Period2 (P2)-7 months, Period3 (P3)-11 months during their 1-year training; and the cytotechnologists only once. A general linear mixed model was used to analyze the results.
The proportion of agreement on interpretations for cytotechnologists, students during P1, and students during P3 were 0.83, 0.62, and 0.70 respectively. The mean task duration in seconds for cytotechnologists, students during P1, and students during P3 were 21.1, 34.6, and 24.9 respectively. The mean number of fixation points for cytotechnologists, students during P1, and students during P3 were 14.5, 52.2, and 35.3, respectively. The mean number of gaze observations of cytotechnologists, students during P1, and students during P3 on region of interest (ROI) 1 were 77.93, 181.12, and 123.83, respectively; and, ROI 2 were 38.90, 142.79, and 92.46, respectively.
This study demonstrated that students had decreased time, number of fixation points, gaze observations on ROI, and increased agreement with the reference interpretations at the end of the training program, indicating that their screening skills were progressing towards the level of practicing cytotechnologists.
本研究报告了眼动追踪技术在确定细胞技术（CT）学生在检查数字图像（DI）时的筛查技能方面的潜力。
在三个地点，由 16 名 CT 学生和 3 名细胞技术员对 25 个妇科细胞学标本的静态 DI 进行连续显示，在计算机监视器上进行评估。在评估过程中，参与者的眼球运动通过 Mirametrix S2 眼动追踪器（iMotions，波士顿，MA）和 EyeWorks 软件（Eyetracking，索拉纳海滩，CA）进行监测。学生在以下时间点完成方案：第 1 期（P1）-4 个月，第 2 期（P2）-7 个月，第 3 期（P3）-11 个月，为期 1 年的培训期间；而细胞技术员仅进行一次。使用一般线性混合模型分析结果。
细胞技术员、P1 期学生和 P3 期学生对解释的一致性比例分别为 0.83、0.62 和 0.70。细胞技术员、P1 期学生和 P3 期学生的任务持续时间（以秒为单位）分别为 21.1、34.6 和 24.9。细胞技术员、P1 期学生和 P3 期学生的固定点数量（以个为单位）分别为 14.5、52.2 和 35.3。细胞技术员、P1 期学生和 P3 期学生对感兴趣区域（ROI）1 的平均注视观察次数分别为 77.93、181.12 和 123.83；ROI 2 分别为 38.90、142.79 和 92.46。
本研究表明，学生在培训计划结束时，在时间、固定点数量、ROI 上的注视观察以及与参考解释的一致性方面都有所减少，这表明他们的筛查技能正在朝着执业细胞技术员的水平发展。
