We built a low-cost system for monitoring human skin conductance responses (SCRs) in a clinical magnetic resonance (MR) scanner during functional imaging. The average scanner-induced conductance noise level was suppressed sufficiently to allow SCR measurements over the full range of SCR amplitudes, and functional image signal-to-noise ratio was unaffected by the skin conductance apparatus. The system may be useful for a variety of imaging studies.
我们构建了一个低成本系统，用于在功能成像期间在临床磁共振（MR）扫描仪中监测人体皮肤电传导反应（SCR）。平均扫描仪诱发的电传导噪声水平被充分抑制，以允许在SCR幅度的全范围内进行SCR测量，并且功能图像信噪比不受皮肤电传导设备的影响。该系统可能对各种成像研究有用。
