In conventional fMRI, the possibilities for remote visual monitoring of a volunteer or patient during scanning are very limited. However, performance during motor paradigms, monitoring of ventilated patients, or patients with movement disorders is often of particular interest. In order to facilitate remote visual monitoring during MRI examinations, an MR-compatible video system was developed and implemented to allow monitoring of the face and the body, separately, with two cameras. The system reliably allows the recording of video data during MRI scanning without affecting MR image quality. The applicability of the system for the online recording of tics during an fMRI study with Tourette patients is demonstrated. Monitoring of a motor task in healthy controls and Tourette patients was possible with exact synchronisation to the fMRI paradigm. Details of system set up and example control measurements are presented. Further, electronic and mechanical components are described in detail enabling easy reproduction of the system.
在传统功能磁共振成像（fMRI）中，扫描期间对志愿者或患者进行远程视觉监测的可能性非常有限。然而，运动范式期间的表现、对通气患者或患有运动障碍患者的监测通常特别令人关注。为了便于在磁共振成像（MRI）检查期间进行远程视觉监测，开发并实施了一种与MRI兼容的视频系统，该系统通过两个摄像头分别对脸部和身体进行监测。该系统能够在MRI扫描期间可靠地记录视频数据，而不会影响MR图像质量。文中展示了该系统在一项针对图雷特氏症患者的fMRI研究中在线记录抽搐的适用性。在健康对照者和图雷特氏症患者中监测运动任务，并与fMRI范式精确同步是可行的。本文介绍了系统设置的细节和示例对照测量。此外，还详细描述了电子和机械组件，以便于该系统的复制。
