我们开发并验证了带有三种新颖工具的回声模拟器，这些工具有助于培训并能够定量和客观地测量精神运动和认知技能。首先，受训者可以看到原始患者图像（不是合成或模拟图像），当在人体模型上操纵模拟传感器时，这些图像会实时变形。其次，增强现实用于视觉引导，该工具通过以 3 维 (3D) 形式显示目标器官以及当前视图平面的位置和解剖学正确视图的平面来帮助受训者进行扫描。第三，我们介绍图像匹配，这是一种利用人脑识别相似性和差异的能力来帮助学员学习对超声图像进行视觉评估的工具。精神运动能力是根据视角误差来衡量的。能力测试模拟器的结构有效性是通过证明其区分新手和专家的能力来建立的。
We developed and validated an echo simulator with three novel tools that facilitate training and enable quantitative and objective measurement of psychomotor as well as cognitive skill. First, the trainee can see original patient images - not synthetic or simulated images - that morph in real time as the mock transducer is manipulated on the mannequin. Second, augmented reality is used for Visual Guidance, a tool that assists the trainee in scanning by displaying the target organ in 3-dimensions (3D) together with the location of the current view plane and the plane of the anatomically correct view. Third, we introduce Image Matching, a tool that leverages the aptitude of the human brain for recognizing similarities and differences to help trainees learn to perform visual assessment of ultrasound images. Psychomotor competence is measured in terms of the view plane angle error. The construct validity of the simulator for competency testing was established by demonstrating its ability to discriminate novices vs. experts.
