英文摘要	This paper presents a novel augmented reality (AR) interactive environment for neurosurgical training. Comparing with traditional virtual reality based neurosurgical simulator, our system provides a more natural and intuitive fashion for surgeons. To achieve holographic visualization of virtual brain on 3D-printed skull (workspace), the first step is to reconstruct the personalized anatomy structure from segmented MR imaging. Then, tailored to the computational power of HoloLens, we employ the mass-spring method to model the mechanical response of brain. After that, a precise registration method is employed to map the virtual-real spatial information, which can overlay the virtual operative brain on workspace. In addition, bimanual haptic interface is also integrated into our simulator, which is more similar with real neurosurgery. In experiments, we conduct accuracy validation on our registration method, as well as the validity test on the developed simulators. The results demonstrate that our simulator can provide high-accuracy augmented visualization effects and deep immersion for novice surgeons.
