Abstract

在这篇论文中,我们概述了一种手术制备方法,该方法仅使用从磁共振成像 (MRI) 中提取的数据对 NHP 中的各种神经外科医生进行实际规划。该协议允许生成3D打印解剖上准确的大脑和头骨的物理模型,以及大脑建模一些机械特性的阿加罗斯凝胶模型。这些模型可以从MRI中提取,使用大脑模型的大脑提取软件,以及头骨模型的自定义代码。制备方案利用最先进的3D打印技术,为凝胶大脑模型制作连接大脑、头骨和模具。头骨和大脑模型可用于可视化颅内脑组织,并在自定义代码中添加颅骨切除术,从而更好地为直接涉及大脑的手术做准备。这些方法的应用是专为神经刺激和记录以及注射手术而设计的,但该系统的多功能性允许将来将协议、提取技术和模型扩展至更广泛的手术范围。
