Transcranial magnetic stimulation is a noninvasive brain stimulation technique. It is based on current induction in the brain with a stimulation coil emitting a strong varying magnetic field. Its development is currently limited by the lack of accuracy and repeatability of manual coil positioning. A dedicated robotic system is proposed in this paper. Contrary to previous approaches in the field, a custom design is introduced to maximize the safety of the subject. Furthermore, the control of the force applied by the coil on the subject's head is implemented. The architecture is original and its experimental evaluation demonstrates its interest: the compensation of the head motion is combined with the force control to ensure accuracy and safety during the stimulation.
经颅磁刺激是一种非侵入性的脑刺激技术。它基于用刺激线圈在大脑中产生感应的原理，线圈会发出强大的变化磁场。目前，其发展受到手动线圈定位缺乏准确性和可重复性的限制。本文提出了一种专用的机器人系统。与该领域以前的方法不同，引入了定制设计以最大限度地提高对象的安全性。此外，还实现了对线圈施加在对象头部的力的控制。该架构是原创的，其实验评估证明了它的优势：头部运动的补偿与力控制相结合，可确保在刺激过程中的准确性和安全性。
