Abstract
PURPOSE: The study investigated whether intra-operative 3D hologram, a computer graphics model of the brain, with mixed reality (MR) technique based on computed tomography-magnetic resonance imaging (CT-MRI) fusion images could be helpful during brachytherapy for brain metastasis. MATERIAL AND METHODS: I seed implantation was performed under MR guidance. RESULTS: of post-operative plan and pre-operative plan were 131.8 Gy vs. 132.0 Gy and 94.8% vs. 94.0%, respectively. The patient's imaging findings together with clinical symptoms were greatly improved at 3 and 6 months after the implantation. CONCLUSIONS: This initial experience suggests that the use of the intra-operative hologram with MR technique based on CT-MRI fusion images helped in brachytherapy guidance. Further research is needed to explore the potential of this approach in neuro-navigation.
