We demonstrate the first use of Optically Pumped Magnetoencephalography (OP‐MEG) in an epilepsy patient with unrestricted head movement. Current clinical MEG uses a traditional SQUID system, where sensors are cryogenically cooled and housed in a helmet in which the patient’s head is fixed. Here, we use a different type of sensor (OPM), which operates at room temperature and can be placed directly on the patient’s scalp, permitting free head movement. We performed OP‐MEG recording in a patient with refractory focal epilepsy. OP‐MEG‐identified analogous interictal activity to scalp EEG, and source localized this activity to an appropriate brain region.

光泵脑磁图在癫痫中的应用。


我们首次在头部运动不受限制的癫痫患者中使用光泵脑磁图（OP-MEG）。目前的临床 MEG 使用传统的 SQUID 系统，其中传感器经过低温冷却并安装在固定患者头部的头盔中。在这里，我们使用不同类型的传感器 (OPM)，该传感器在室温下运行，可以直接放置在患者的头皮上，允许头部自由移动。我们对一名难治性局灶性癫痫患者进行了 OP-MEG 记录。 OP-MEG 识别出与头皮脑电图类似的发作间期活动，并将该活动定位到适当的大脑区域。
