背景：在许多远程医疗应用中，在需要时正确使用医疗设备对于提供适当的服务至关重要。一些应用可能需要未经培训的人员与医疗设备和患者进行交互：运输中的护理交付，军事行动，家庭护理和远程医疗培训。医疗器械的正确操作和与患者身体的正确连接至关重要。在这些情况下，增强现实的定制应用程序可以通过在需要时指导未经培训的人来提供有效的支持。本研究的目的是探索在远程医疗应用中使用增强现实的可行性，通过促进任何不熟练的人可以接受的使用生物医学设备。特别是，建立了一个原型系统，以估计如何未经培训的用户，有限或没有知识，可以有效地与ECG设备进行交互，并正确地将ECG电极放在病人的chest.Methods：一个增强现实应用程序，以支持未经培训的用户在执行ECG测试。简单的标记物连接到ECG设备和患者的胸部，允许相机校准。一旦物体及其在空间中的姿态被识别，当前场景的视频就被实时地丰富起来，包括额外的指针、文本框和音频，以帮助未经训练的操作员执行适当的操作序列。对ECG设备的所有按钮、开关、端口以及心前区导联的位置进行编码和指示。还包括一些用户的语音命令，以提高可用性。结果：十名未经训练的志愿者在增强现实的支持下，能够首先对人体模型进行完整的心电图测试，然后在合理的时间内对真实的患者进行完整的心电图测试（平均约8分钟）。胸电极的平均定位误差小于3毫米的人体模型和小于7毫米的真实的病人。这些初步研究结果表明，开发的应用程序和临床ECG recording.Conclusion的有效性：此应用程序可以适应支持使用其他医疗设备以及其他远程医疗任务，它可以与平板电脑或智能手机进行。
Background: In many telemedicine applications, the correct use of medical device at the point of need is essential to provide an appropriate service. Some applications may require untrained people to interact with medical devices and patients: care delivery in transportation, military actions, home care and telemedicine training. Appropriate operation of medical device and correct connection with patient's body are crucial. In these scenarios, tailored applications of Augmented Reality can offer a valid support by guiding untrained people at the point of need. This study aims to explore the feasibility of using Augmented Reality in telemedicine applications, by facilitating an acceptable use of biomedical equipment by any unskilled person. In particular, a prototype system was built in order to estimate how untrained users, with limited or no knowledge, can effectively interact with an ECG device and properly placing ECG electrodes on patient's chest.Methods: An Augmented Reality application was built to support untrained users in performing an ECG test. Simple markers attached to the ECG device and onto patient's thorax allow camera calibration. Once objects and their pose in the space are recognized, the video of the current scene is enriched, in real-time, with additional pointers, text boxes and audio that help the untrained operator to perform the appropriate sequence of operations. All the buttons, switches, ports of the ECG device together with the location of precordial leads were coded and indicated. Some user's voice commands were also included to improve usability.Results: Ten untrained volunteers, supported by the augmented reality, were able to carry out a complete ECG test first on a mannequin and then on a real patient in a reasonable time (about 8 minutes on average). Average positioning errors of precordial electrodes resulted less than 3 mm for the mannequin and less than 7 mm for the real patient. These preliminary findings suggest the effectiveness of the developed application and the validity of clinical ECG recordings.Conclusion: This application can be adapted to support the use of other medical equipment as well as other telemedicine tasks and it could be performed with a Tablet or a Smartphone.
