Abstract:A high openness eight-channels array head coil is designed based on the needs of a DBS Robotic Surgery System. The function circuit of this array coil is successfully integrated into a rectangular space of 3.76 cm×3.54 cm to save space after simplifying typical RF receive chain in the MRI system, which feasibility is proved by imaging experiment. In order to meet the needs of the needle insertion space for the DBS surgical robot, optimize the current head receive coil. The eight-channels phased array coil with highly open space on both top and front size is designed and simulated by HFSS. Its return losses of all coils reach -40dB, and the adjacent channels are successfully decoupled. This coil has a good feasibility for the DBS robotic surgery system with real-time MRI navigation.
