论文摘要
本文提出了一种基于9 DOF IMU的新型医疗设备，以帮助更精确地执行EEG考试中的电极放置任务。该工具精确地告诉操作员是否正确遵循10-20电极放置系统。手动任务至关重要且耗时，因为所有电极必须正确且非常精确地放在患者的头部。黄金标准过程是手动的，尽管可以应用多个医疗设备（开发到其他类型的医疗程序）来提高电极放置的精度，但它们仍然非常昂贵。拟议的医疗设备仅基于9 DOF IMU的传感器以及微处理器的处理能力，从而降低了设备的价格。此外，与基于红外视觉的系统相比，设备的大小也会减小。开发的系统包括一个可视化子系统，该系统可视化电极在患者的虚拟头上的位置，使用特定工具，3列列器，在指向患者头时接收和可视化医疗设备的3D姿势。初步结果显示了所提出的设备的有效性。
The paper proposes a novel medical device based on a 9 dof IMU to help health professionals performing more precisely the electrode placement task in EEG exams. The tool precisely tells the operator if the 10-20 electrode placement system is being correctly followed. The manual task is of major importance and time consuming, because all the electrodes must be correctly and very precisely placed in the head of the patient. The gold standard process is manual, and although several medical devices (developed to other types of medical procedures) can be applied to increase the precision of the electrode placement, they are still very expensive. The proposed medical device, based only on the sensors of a 9 dof IMU, and the processing capabilities of a microprocessor, diminish the price of the device. Moreover, the size of the apparatus is also diminished, when compared with infrared vision based systems. The developed system includes a visualization subsystem that visualises the position of the electrodes in a virtual head of the patient, using a specific tool, 3DSlicer, to receive and visualise the 3D pose of the medical device when point to the patient head. Preliminary results showed the validity of the proposed device.
