对 4 年期间 5,717 名航空安检员在旅客行李 X 射线图像中检测违禁物品的表现进行了分析。本研究中使用的衡量标准是 X 射线能力评估测试 (X 射线 CAT) 的检测性能，并且该衡量标准的性能是每年获得的。在两次测试之间，安检员使用名为 X 射线导师 (XRT) 的自适应计算机培训系统在违禁物品检测任务中进行了不同数量的培训。对于 XRT 和 X 射线 CAT，违禁物品分为枪支、刀具、简易爆炸装置 (IED) 和其他违禁物品。对训练和测试数据进行横断面和纵向分析。两种类型的分析都表明，由于对所有 4 个项目类别进行 XRT 训练，X-Ray CAT 性能有了显着提高。研究结果表明，通过常规 XRT 培训，可以大大提高安检员检测乘客行李 X 射线图像中违禁物品的能力。
The performance of 5,717 aviation security screeners in detecting prohibited items in x-ray images of passenger bags was analyzed over a period of 4 years. The measure used in this study was detection performance on the X-Ray Competency Assessment Test (X-Ray CAT) and performance on this measure was obtained on an annual basis. Between tests, screeners performed varying amounts of training in the task of prohibited item detection using an adaptive computer-based training system called X-Ray Tutor (XRT). For both XRT and X-Ray CAT, prohibited items are categorized into guns, knives, improvised explosive devices (IEDs), and other prohibited items. Cross-sectional and longitudinal analyses of the training and test data were performed. Both types of analysis revealed a strong improvement of X-Ray CAT performance as a result of XRT training for all 4 item categories. The results of the study indicate that screener competency in detecting prohibited items in x-ray images of passenger bags can be greatly improved through routine XRT training.
