We present the design, setup and results for a magnetic navigation system for small animal stereotactic neurosurgery. Our system tracks the position of thin (diameter 0.5 mm), magnetized ferromagnetic probes inserted into brains of small animals, e.g. rats, for electrophysiological recordings. It is used in combination with the spherical assistant for stereotactic surgery (SASSU) robot to obtain online feedback of the probe's position. Navigation is based only on the static magnetic field generated by the probes thus no external excitation or wires are needed.
我们展示了一种用于小动物立体定向神经外科手术的磁导航系统的设计、设置和结果。我们的系统可追踪插入小动物（如大鼠）大脑中的细（直径0.5毫米）磁化铁磁探针的位置，用于电生理记录。它与立体定向手术球形辅助机器人（SASSU）结合使用，以获得探针位置的在线反馈。导航仅基于探针产生的静磁场，因此无需外部激励或导线。
